This has the same problem that I mentioned before:
in one place (in (2)) foo:bar means one thing.
in some other place (in (4)), it means something else.
I think it is no good for a macro.

This compounds the same problem. In (1), <http://purl.org/dc/terms/creator>
means
"http://purl.org/dc/terms/creator"^^rif:iri.
In (3), the same thing means just http://purl.org/dc/terms/creator

This is part of the problem mentioned in (1).
What was wrong with my much simpler proposal to allow macro-expansion (by
simple concatenation) everywhere this stuff occurs unquoted (like after ^^
and inside <...>)?
