# This cop checks for use of the helper methods which reference
# instance variables.
#
# Relying on instance variables makes it difficult to re-use helper
# methods.
#
# If it seems awkward to explicitly pass in each dependent
# variable, consider moving the behaviour elsewhere, for
# example to a model, decorator or presenter.
#
# @example
# # bad
# def welcome_message
# "Hello #{@user.name}"
# end
#
# # good
# def welcome_message(user)
# "Hello #{user.name}"
# end
