You can use Class::MOP to figure this out pretty easily.

my @methods = Class::MOP::Class->initialize('My::Package')->get_all_me
+thods;

What is in @methods is an array of Class::MOP::Method objects which you can call the following methods on:

• name - the local method name
• package_name - the package where the method is defined
• fully_qualified_name - the package name + name
• body - returns the code ref

It should be noted that unlike Class::Inspector and the newer Class::Sniff, this will honor the MRO (Method Resolution Order) you have chosen to use, so in 5.10 (or under Class::C3) it will return a correct method list if you use the c3 MRO instead of the standard dfs (depth-first-search) MRO.
