# I have a class that includes a single plugins module which in turn includes
# separate plugin modules. I'd like to be able to call class methods from each plugin
# without having to wrap the methods in the `self.included .. class_eval`
# Is there anyway I can achieve this nicely?, I'd want to use plugins as per the
# IdealPlugin module
