That is what I have been trying to say, imho "any" should have the same
NOTICE as opaque has, since it is potentially dangerous.
I would suggest a warning NOTICE for opaque and not depricate it.

Imho the NOTICE should *not* go away.

If we want "any" in the future, it should imho always be passed a "safe"
Datum that includes type info. This will allow us to create a type "any"
that does not have the pitfalls of opaque.
