There was a problem hiding this comment.
For ArrowFunctionExpressions, we now incorrectly assume components to be of type 'Other' as they don't have an identifier. There are optimisations and assumptions that depend on getting this type correct, which cause incorrectly generated code.

This was a pet peeve where our playground could only compile top level
FunctionDeclarations. Just synthesize a fake identifier if it doesn't
have one.
