// An object path is a textual and (with training) human-readable encoding

// of a sequence of destructuring operators, starting from a types.Package.
|
||||
// The sequences represent a path through the package/object/type graph.
|
||||
// We classify these operators by their type:
|
||||
//
|
||||
// PO package->object Package.Scope.Lookup
|
||||
// OT object->type Object.Type
|
||||
// TT type->type Type.{Elem,Key,Params,Results,Underlying} [EKPRU]
|
||||
// TO type->object Type.{At,Field,Method,Obj} [AFMO]
|
||||
//
|
||||
// All valid paths start with a package and end at an object
|
||||
// and thus may be defined by the regular language:
|
||||
//
|
||||
// objectpath = PO (OT TT* TO)*
|
||||
//
|
||||
// The concrete encoding follows directly:
|
||||
// - The only PO operator is Package.Scope.Lookup, which requires an identifier.
|
||||
// - The only OT operator is Object.Type,
|
||||
// which we encode as '.' because dot cannot appear in an identifier.
|
||||
// - The TT operators are encoded as [EKPRUTC];
|
||||
// one of these (TypeParam) requires an integer operand,
|
||||
// which is encoded as a string of decimal digits.
|
||||
// - The TO operators are encoded as [AFMO];
|
||||
// three of these (At,Field,Method) require an integer operand,
|
||||
// which is encoded as a string of decimal digits.
|
||||
// These indices are stable across different representations
|
||||
// of the same package, even source and export data.

//
|

// S[A].Foo, S[A].Bar
