Things can get somewhat ambiguous:
module M (module A value B type C)
Granted, 'module' and 'type' are keywords and cannot be value names, but:
* this introduces ambiguities for the parser, even if they are resolvable
* this is hard to read for humans
* it seems likely that we'll be getting even more qualifiers in the
future ('kind'?)
