Yes, or namespace A[[nonsense]]::B {}. Those cases are easy to fix,
but namespace [[attribute_in_proper_location]] A {} seemingly caused
weird barfing. That's why I didn't put in the rejection of the former,
I'd prefer
to figure out the latter and the former at the same time, and I'd prefer doing
that once the basic facility is in. Yes, partly because I'll travel tomorrow. :)
