Redefinition warnings in SupportsFeatureMixin

[djberg96]

With warnings enabled you'll see that the SupportsFeatureMixin triggers lots of redefinition warnings:

# sf_test.rb
require 'active_support'
require 'active_support/core_ext/object/blank'
require_relative 'supports_feature_mixin' # Assume sf_test.rb and supports_feature_mixin.rb are in same directory

class Post
  include SupportsFeatureMixin
  supports :publish
  supports_not :migrate, :reason => 'Migrate not supported'
end

p Post.supports?(:publish)
p Post.supports?(:migrate)
