- object.union
- object.union_n
- treat negative integers as two separate tokens (Sub and Number)
when seen in arithmetic expressions
- 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
- Update opa.passing

- 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

Number is implemented using rust_decimal::Decimal which uses a 96 bit mantissa.
TODO:
a) Support u64, i64 variants
b) Determine desired semantics for floating-point
c) Determine desired big integer length
d) Explore other big int/big float crates

1. Numeric indices will be converted to strings for refs beginning with `data`
if there is not valid numeric key
2. Error out if input document already contains value for a ref

When evaluating rules, upon error the last pushed scope wasn't being
popped from the stack of scopes. This causes incorrect behavior
when there are multiple definitions for the same rule name.
The fix is to make sure that the scopes are popped manually upon encountering errors.
Once the interpreter logic is locked down, then we need to clean up scope management
using Drop functions so that the cleanup happens even during short circuited return.

Rename compare.rs to comparison.rs to match OPA documentation of builtins.
Also update loop handling to ensure that the current scope is restored after
each iteration of the loop so as to undo side effects of the iteration.

Support "var = value", "value = var", and "var = var"
Fall back the '=' to comparsion when both operators are defined
Correctly support variable shadowing with "var := value"
Also, remove the unused Variable struct

Only scalars, composites and comprehensions containing scalars are supported.
This will be changed as OPA fixes bug with default values
