You need to distinguish between two types of functions: ones which
use namerefs, and ones which do not.
If a function doesn't use name references, then you may safely use
local variables with any names you like. Nothing has to change.
If a function is going to use a name reference, then you need to
bullet-proof it from head to toe. All local variables have to be
mangled to minimize the chance of collisions. It's an entirely
different problem.
