In-band signaling is error-prone. It's not great that you had to add an explanatory comment to every call site.

I'd prefer to see some refactoring here:

(1) Rename findScopedProperty to resolve;

(2) Change resolve to return an object, ResolveResult, describing what it found.

(3) Add "I found a block-scoped variable" as a feature to ResolveResult.

(4) Add optimizations to take advantage of (3).
