I don't particularly like this duplication, in fact I hate it. But since this
file is a mess, any suggestion at making this cleaner would probably involve
burning this file to the ground first. So I'll live with this duplication for
now I guess.

Agreed. We need to factor out into a routine to parse, rewrite, scope analyze,
and commit the results to SharedFunctionInfo and ScopeInfo objects.
