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"] ~~~~ -- https://bugs.ruby-lang.org/
