The code in Carp::Heavy doesn't access lexical variables but the parameter arrays @_ of calling functions up the stack. This is enabled by calling caller() from the package DB, presumably an efficiency hack.

To access lexical variables in calling subs there's the module PadWalker available from CPAN. All I remember from playing with it once is that it wasn't quite as easy to use as I would have wished.
