# This check reports code that uses +for+ loops as in:
#
# for user in @users
# do_something(user)
# end
#
# The use of for loops in Ruby is contrary to the language's basic concept of iterators. The above statement would better be written as:
#
# @users.each do |user|
# do_something(user)
# end
#
# ==== Applies to
#
# * +for+ loops
