"no variable or argument declarations are necessary."

[Neil Hodgson]

    C++ and C# are converging with implicitly typed languages to the 
extent that many declarations will be able to omit types. In the next 
C++ standard and in C# 3.0 it may be possible to write, where Fn is a 
function returning any particular type:

auto spam = Fn();	// C++0x
var spam = Fn(); 	// C# 3.0
