Perhaps you want to look at exceptions:

(Note: this is something I wrote.)
It's not exactly what you want, but you may be able to re-engineer your
program using Object Oriented exceptions. Also look at Exception::Class,
which has less dark magic than Error.pm, but has less syntactic sugar. (which
in Error.pm's case is rather error-prone).
