Ruby

Since unbound methods from modules can now be bound to any object, I use them a lot.
I think it would be very natural to be able to convert them to Proc:

module UnboundMethod def to_proc return lambda do |obj,*args,&b| self.bind(obj).call(*args,&b) end end end 

This would allow things like

module Foo def foo self+"foo" end end ["bar","baz"].map(&Foo.instance_method(:foo)) => ["barfoo", "bazfoo"]
