Full analysis is probably impossible[1], but static analysis can be
'good enough' for most purposes. It's certainly a lot easier if we
have only have local refs to deal with.

But, there is a limit of about 200 for the number of local variables
per chunk [2]  So one could realistically hit some hard limits.
