Ruby

The behavior of Object#method changed in 2.3 when using it to compare aliases. The change is best illustrated below:

module Foo def foo end alias_method :foo_foo, :foo end class Bar include Foo alias_method :bar, :foo end bar = Bar.new bar.method(:foo) == bar.method(:bar) # true in Ruby 2.2 # false in Ruby 2.3 and 2.4 bar.method(:foo) == bar.method(:foo_foo) # true in Ruby 2.2, 2.3, 2.4 

Was this an intentional change in 2.3 or a regression?
I tested this with 2.2.3, 2.2.7, 2.3.0, 2.3.3, 2.3.4, and 2.4.1.
