sub classing kills your code... :(

class MyString < String
end

p MyString.new('foo_').upcase

(eval):4:in `bind': first argument must be an instance of String (TypeError)
	from (eval):4:in `upcase'
	from hook.rb:24


ps. Dave, are you tring to create anonymous method so that you can use
it in hooked method *and* it can't be messed by whomever sub-classes it?
