Function Objects

In C++ even the function call operator (parenthesis operator) can be overloaded. Allows for creation of objects that can be used like functions.

class biggerThanThree {
		bool operator () (int v)
			{ return v > 3; }

Can be used to find the first value bigger than 3, for example.
