RFC: lethal - lexical exceptions for Perl
I've been scratching a long-time itch of mine, which is that while Perl allows me to use Fatal to get subroutines and built-ins to throw exceptions on failure, such a change was always done on a package-wide, rather than lexical (block) basis.

However with Perl 5.10 we have the ability to fix that, and I've put together a proof-of-concept module that enables exception-throwing subroutines on a lexical basis.

I'm looking for input into its naming, interface, and concept in general. Rather than filling up a blog post with it, you can read the node on PerlMonks.
