Well, that was on purpose, to match the lex interface.
I'm unsure it is wise to invite the scanner into the
parser's namespace: we might have to deal with unwanted
collisions.

That was not an expected feature, but I see Joel picks up the
ball :)

If we start "parsing" namespace names, we will have a million

"foo::", etc.?
