# Introspect module for shoop. Expands the OBJECT class with an introspect
# method, that can list all methods and variables that are defined on a
# class.
#
# Smell the Java. LGPL copyright 2000 by Adam Heath <doogie@debian.org>
## When called it will print out a brief synopsis of the methods and
## variables defined for the current object. If passed the parameter
## C<resolve>, it will walk the parent tree, and print out everything,
## all the way back to the base OBJECT.
##
## If you are going to use introspection, it is suggested you C<use>
## it early, as the introspection hooks are not normally enabled.
# Enable introspection inside _shoop
_shoop_introspect=1
