I can't see why it *should* work.

The way I've always thought about it is that templates are parameterised
namespaces.  Since (/*alias*/ TC) is a type parameter, it makes no sense
to pass in a namespace, whereas (alias TC) *does* since it's an alias to
an arbitrary symbol.

I dunno; maybe it's just my way of rationalising it :P
