I have a distinct sense of deja vu here.  I think this idea, or something
isomorphic to it, was previously discussed with some other syntax details.
I'm too lazy to go searching the archives right now, but I suggest that
you try to find that discussion and see if the discussed syntax seems
better or worse than what you mention.

I think it might've been along the line of @extschema:nameofextension@,
which seems like it might be superior because colon isn't a valid
identifier character so there's less risk of ambiguity.
