Frog generates non-working code for multiple closures over one mutable variable.

This happens only in loops (reentrant nested scopes).

See test case: http://codereview.chromium.org/8602013/

BTW, I think this happens any time you mutate something after capturing it.
Yeah, we need to be lifting binding against a scope object that we create to hold mutable captures, rather than binding to the values.
