You can get the subroutine source from a reference using B::Deparse.

Hm. That's interesting. What I was really looking for was a way to find the string name of a sub, not the source for it. IOW, suppose I had: 

package my::Plugins::SomePlugin;

sub myhandler {
    do_something();
}

my::Error::register(\&myhandler);

[download]
Then inside my::Error::register() somehow I could convert the ref I'd been passed back into the name of the sub (in this case the string "my::Plugins::SomePlugin::myhandler").
