Can't use << on a string variable?

[JohnDoe1]

Shouldn't this be allowed? I'm using Visual Studio 2008 and getting the following error when I try using string variables with the << operator.

error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const std::string' (or there is no acceptable conversion)

IE. The following does not work:

std::string name = "John";
std::cout << "Hello " << name << "\n";

I don't remember this always being the case, though I could be wrong. Is this VC's fault or mine?

I see no reason why that shouldn't work.
