# Sort globbed results by default in Ruby 3.0.
# This cop checks for redundant `sort` method to `Dir.glob` and `Dir[]`.
#
# @example
#
# # bad
# Dir.glob('./lib/**/*.rb').sort.each do |file|
# end
#
# Dir['./lib/**/*.rb'].sort.each do |file|
# end
#
# # good
# Dir.glob('./lib/**/*.rb').each do |file|
# end
#
# Dir['./lib/**/*.rb'].each do |file|
# end
