# Seeing really confusing RSpec output like this?
#     Failure/Error: obj.will_paginated_array.map(&:id).should =~ [foo.id, bar.id]
#       expected: [1, 2]
#            got: [1, 2] (using =~)
# (WillPaginate::Collection#map returns WillPaginate::Collection instance)
# This is due to how OperatorMatcher simply does a lookup of the class of the actual
# result rather and checking a hash rather than using #is_a?(klass)
#
# This snippet below will make it work again.
