That's compile-time detection of whether the object has some member 
function with a given signature or not. You can detect mostly everything 
but constructors and member-only operators, actually.

It's too bad there isn't a Boost library to do just that. It's true that 
with concepts, though, it becomes less useful.
There are probably bits in some places in Boost but I never knew where 
they were.
