And the fun potential for memory leaks with nested closures.

You can do that without using Error.pm's try/catch stuff by simply using
Error's exception objects or the Exception::Class provided exception
objects.
AFAICT, Tatsuhiko's module is designed to work with either of those types
of objects transparently, but it provides an alternate mechanism for
catching exceptions.
And anything inspired by my Sig::PackageScoped module scares me, but its
an interesting idea ;)
