Summary: Safely and cleanly create closures via string eval
Description:

String eval is often used for dynamic code generation. For instance, Moose
uses it heavily, to generate inlined versions of accessors and constructors,
which speeds code up at runtime by a significant amount. String eval is not
without its issues however - it's difficult to control the scope it's used
in (which determines which variables are in scope inside the eval), and it
can be quite slow, especially if doing a large number of evals.

This module attempts to solve both of those problems. It provides an
eval_closure function, which evals a string in a clean environment, other
than a fixed list of specified variables. It also caches the result of the
eval, so that doing repeated evals of the same source, even with a different
environment, will be much faster (but note that the description is part of
the string to be evaled, so it must also be the same (or non-existent)
if caching is to work properly).
