Thanks for answering, this sounds like a good idea. Can you tell me how can I get a list of all currently populated namespaces? %INC contains only namespaces tied to a physical .pm file, and if a file has several package X pragmas I will examine only the first one.

Btw if you are curious the ickyness comes form the fact that I am fooling around with exception handling, and I had this nice idea of globally redefining Carp::croak() and Carp::confess() to throw an object except of a string (I know I know it is far from best practice to fool around with core modules, but I really liked the idea, an wanted to see if it can actually work). Since Carp is a very central module it is being used all over the place in many other modules, and hence it is
1) impractical to change all calls to it Carp::x()
2) impractical to attempt to load my exception handler before any references to Carp.
The two subroutines that must be redefined are trivial one-liners, thus I figured it should do no harm:
sub croak   { die  shortmess @_ }
sub confess { die  longmess  @_ }

Addition: Why I don't simply overload CORE::die? Because for one it can be overloaded by someone else, and more importantly module authors sometimes examine $@ and finding an object there has a very remote chance of breaking stuff (although I have backwards compatible stringification of '<error> at <file> line <ln>.' On the other hand croak is clearly designed to be seen by the user, who in this case will be expecting an object.
