Is the following legal?

	const int& positive(const int& value)
	{
		if (value<0)
		{
			return 0;
		}
		else
		{
			return value;
		}
	}

If so, I presume it's also valid in the general case:

	const ClassType& func(const ClassType& value);

and that the return of a literal generates a temporary which is bound to 
the reference returned and persists until the completion of the full 
expression enclosing the function call (or the destruction of a reference 
variable to which the returned reference is subsequently bound).

I've searched through the April 95 WP for a definitive answer.
8.5.3. [dcl.init.ref] seems to imply this usage is valid (by 
analogy to the binding of temporaries to const reference parameters).
