That's not a TypeTuple, though, it's a built-in tuple.

void main()
{
	writeln(func());
}

TypeTuple!(int, string) func()
{
	return tuple(1, "a"); //Error
}

Nor does it work the other way around:

Tuple!(int, string) func()
{
     return TypeTuple!(1, "a"); //Error
}

How would this work for some hypothetical built-in syntax?

#(int, string) func()
{
     return tuple(1, "a"); //Error?
}
