Or as I see it working in the more verbose case:

T foo.opAssign(T bar)
{
	// code goes here.
}

If namespaces lead to that kind of ability then they seem pretty nifty.

That seems pretty useful.  Maybe it doesn't have to be namespace.  Use
scope or auto instead.  scope seems appropriate, though it may be asking
for ambiguities.  I can live without this though if it is too drastic.
