If you're on 1.9, you can use Method#source_location to see where it's 
source was defined (at least).

This tool leverages that:
ri_for gem

C:\> gem install ri_for
C:\...>script\server
# drops into a debugger
(rdb:1) require 'ri_for'
(rdb:2) Devise::Mapping.ri_for :some_method
(rdb:2) Devise::Mapping.desc
