I think you're trying too hard turning Perl into just another C clone.
Dynamic variable allocation and freeing, like this, are one of the main
selling points for Perl as a language.
Note that %baz can, as values, also contain references to other
lexically scoped varibles, like \$foo and \$bar. No prototping around
that.

You could, theoretically, create special versions of "my", or a "my"
with an attribute, so that these declared variables are kept out of the
normal lexical pool, and garbage collected in a more elaborate way,
perhaps even reference counting.
