Well, going forward, I know I would much rather have to say "mytbl.mycol" than
have to say "myfunc.myparam". And I certainly would want to expect that when
one says "... as foo" that this "foo" is treated as a declaration unambiguously
and is never substituted for some parameter or there be other grief as I seem to
