It _is _ bit funny, but Ibelieve that it comes from permitting empty template
parameter lists. Without that, recursion with eponymous templates would become
problematic. e.g.
enum template myTemplate(T...)
{
static if(T.length == 0)
enum myTemplate = 42;
else
enum myTemplate = T[0] * 3 + myTemplate!(T[1 .. $]);
}
needs to be able to take an empty parameter list. It's probably possible to
make that work without allowing an outright empty parameter list that isn't
even a variadic template, but I suspect that it's just easier to allow it.
