# Using integrate is just like using include except the
# module included is a reconstruction of the one give
# via commands given in a block.
#
# Convenient commands available are: #rename, #redef,
# #remove, #nodef and #wrap. But any module method
# can be used.

# module W
# def q ; "q" ; end

# class X
# integrate W do
# nodef :y
# end
# end
#
# x = X.new
# x.q #=> "q"
# x.y #=> missing method error
#
# This is like #revisal, but #revisal only
# returns the reconstructred module. It does not
# include it.
