I realize this is a ludicrous question for something that takes less than 2 seconds to implement. But I vaguely remember reading that one was introduced with the new standard.
I grep'ed VC10's headers and came up with nothing. Can you help? It's bugging me! :)
edit:
On second thought, the new functor I was remembering was probably the unrelated std::default_deleter
.
You could always write a no-op lambda: []{}
