- Disable default features in dependencies
- Use anyhow::Error::msg to map errors. Note: anyhow will itself be removed later.
- lazy_static/spin_no_std used in no_std environments
- ensure_no_std binary is built to target thumbv7m-none-eabi to ensure that
there are no std dependencies. thumbv7m-none-eabi target has no std support.
- The opa-no-std feature enables only those Regorus features that work with no_std.
- Enable tests with no_std
- Update sizes of regorus binary in README.md
- Ensure that regorus example can be built with only std
- Ensure that regorus example can be built with no_std

If a rule is written to produce a constant value, then not all iterations of loops
within it need to be executed. Execution can stop via early return once the first iteration
that produces a value has been executed.
This brings forth the question : What if one of the subsequent iterations would have resulted
in an error?
e.g:
x {
[1, "hello"][_] + 1
}
Such errors are not raised; consistent with OPA.

Second lookup of an object rule without fully qualified path, resulted
in returning the object instead of the requested field.

Previously we used to rely on whether there was a value in the
data document for a given rule path. This approach cannot handle
the case of evaluating a.b when a.b.c has been evaluated but
a.b.d has not been evaluated. Upon evaluating a.b.c, the data document
will already have a value of a.b even though a.b.d has not yet
been evaluated.
Hence we need to keep track of evaluated rules separately.

* `arc` feature to make engine usable from multiple threads.
`arc` is turned on by default. When enabled, std::sync::Arc
will be used instead of std::rc::Rc. The former makes regorus
types like Engine, Value, ast nodes etc Send, allowing for
usability from multiple threads.
Arc would add a performance overhead though since the reference
counting will now become atomic.

Allow `import input` instead of erroring out.
This import is redundant and has no effect.
Emit `print` messages to stderr onstead of stdout.

Implement `import rego.v1`
https://www.openpolicyagent.org/docs/latest/policy-language/#the-regov1-import
- `if` required before rule body
- import rego.v1 automatically imports future.keywords
- handle import shadowing
- data, input cannot be shadowed
- deprecated functions as disallowed
- rules must have assignment or body
- `contains` required for parital set

- Separate out public, unstable and internal APIs.
- Cleanup README.md and include it as the crate documentation.

- parser: allow non-string index at any position; not just last
- impl Default for Context
- Fix width of OPA test results table
- Allow non string compoenent anywhere in rule ref; not just as last item.
- Normalize want_result before comparison.
- Ensure that object rules are created even if no definition succeed,
- Sort want_result values for "refheads/general, multiple result-set entries"
The entries are in reverse order of how OPA and regorus produce.
- Emit PASS status for each OPA testpoint
- Detect rule conflicts

- ignore worktrees
- feature guard time module
- Apply with modifiers before evaluating loop expressions
- Support value modifier for functions
- stubs for http.send and io.jwt.decode_verify
- Initialize with-document after initializing init data
- In case of conflict, with modifier override init-data values.
- In case of conflict, subsequent with modifier overrides earlier ones.
- Ensure that zero parameter functions are evaluated and added to document
- opa.runtime builtin
returns:
- git commit hash
- environment vars
- regorus features enabled
- builtins available
- deprecated builtins available
- If `sort_bindings` is specified, sort the bindings in OPA tests
- gather inputs, used vars and comprehensions in with modifiers
- For refs starting with `data`, ensure that modules are evaluated before looking up
value of the expression. Thie ensures that modules that have only been partly populated
(E.g via with mods) are completely evaluated before the value is looked up
- Mark rules overridden using with modifiers are evaluated.
- Exclude env vars in opa.runtime.
- Include regorus version in OPA runtime
- update to opa v0.60.0
- scheduler: Handle function refs in with modifers. Error out only if
a truly undefined ref.
- Handle undefined params, parameter expression evaluation errors before
applying with modifiers.
- When applying with modifiers, first determine whether the target is a
function. If so, handle cleanly.
- concat: raise error only in strict mode
- In strict mode, propagate errors raised by function rule execution
in case of multiple function definitions for same rule
- skip "withkeyword/builtin-builtin: arity 0" test which can never pass.
- When a mock has is being applied, clear with_function so that
other mocks won't be applied during the evaluation of the mock.
- Ability to specify strictness in tests

The walk builtin generates values and implicitly creates a loop over the values.
Hoist walk calls as loops and handle them. Also handle cases where return value
is bound to an extra parameter.

- Switch to scientific crate. Large values are printed in scientific notations.
Regular values are printed as u64, i64 or f64.

- treat negative integers as two separate tokens (Sub and Number)

- Ensure that fully query string is parsed
- Evaluate queries in a separate module instead of the last read module.
This correctly handles queries of the form `x = data.test.y` where x is
already a ref in `data.test`
- Handle queries producing multiple outputs in test infrastructure
- Add tests for engine
- Add tests locking down valid queries

- Remove unnecessary memory allocations
- Add --non-strict flag
- Ensure that only empty modules (ones without rules) are initialzed prior to evaluating rules.
- Record rule as entry for each of its prefixes.
For example, for a rule a.b.c =... in package test, record it in
rules["data.test.a"], rules["data.test.a.b"] and rules["data.test.a.b.c"]
This allows evaluating the correct list of rules based on expessions
a.b.c, a.b, a, data.test.a.b.c, data.test.a.b, data.test.a
