It's already been decided there _will_ be a loop macro in the WG2 standard,
although it's more likely to be based on one of the Scheme loops than on
CL loop.

And it will just be a portable library that users can ignore if they want and
won't place any burden on implementers.

POSIX time is a very broken design which has caused real
crashes in systems, and I'm convinced it's impossible to build
a reliable system on top of it.  Everyone admits it's broken,
so it's worth discussing whether we can do something sane about
patching up the mistake.

We can certainly leave time altogether out of the WG1 standard,
but I don't want to incorporate designs that are broken and may
even eventually be fixed - even if it takes 50 years.

Actually, you have it backwards.  R6RS requires full Unicode support,
which was one of the (many) complaints against it, and is why the WG1
standard doesn't require anything beyond ASCII.
