> the module, in which the login function appears?
Don't know what you mean with "appears" ..
- If you want to know which modules actually use this method (!) , ...
... you could use caller inside the method to report the locations at runtime.
(not sure if applying B::Xref helps with methods)
- If you want to know where the method was defined ...
... you can might be able to use ->can to get the function's reference
and use introspection with B to find the origin. (untested, will update code)
- my $c_ref = $obj->can("method_name") will return the reference of the method
- my ($file, $line) = get_code_location($c_ref) in Sub::Identify allows you to retrieve the original source location
the latter can be done without extra module using some half cryptic B code, but I'm reluctant digging it out.
IIRC an example can be found in the O'Reilly book "Perl Hacks" or google is your friend.
