Is there a way to get a template function return type with

template arguments.
I'm asking because there's potentially recursive template
instantiation if I do try to instantiate it.
What you want cannot work in the general case. The template
function must be instantiated.
T identity(T)(T t)
{
return t;
}
It's not possible to calculate the type of the return value of
`identity` until it is instantiated with a type.
