in reply to Exception Safe Perl

I definitely recommend starting with Exception::Class. Among other things, its ability to let you define a hierarchy of exceptions should simplify what is necessary for some of your objectives (independent default types and different "levels" of errors).

Update: I just noticed Simon Cozen's new article "Ten Things You (Probably) Didn't Know About Perl" on TPJ. It mentions the sigtrap pragma as another way of trapping signals. YMMV.
