I really miss those features:

Module#prepend (but there is a ticket for that, if I remember correctly):

	module Extension
		def to_s
			"< " + super + " >"
		end
	end
	
	class Base
		prepend Extension
		def to_s
			"base"
		end
	end

	Base.new.to_s # => "< base >"

And the other one is proper module propagation:

	module Extension
		def foo
			42
		end
	end

	Enumerable.send(:include, Extension)
	Array.new.foo # => 42

The latter being not yet the case is rather confusing and not correctly fixable from within Ruby.

@matz: At Euruko you mentioned something aboute 'scoped monkey patches' and I was told you
made some Traits proposal at the dev meeting at RubyKaigi but I was unable to find infos on that.
Maybe it will solve this issues.
