Re: SRFI-2 (and-let*) Implementation for Guile

[Rob Browning]

I sent this to Oleg and Dale, but forgot to include the gnu addresses,
and I just wanted to keep you posted.  Presuming the guile developers
are interested, I'm going to try and get licensing straightened out
for as many SRFIs as possible, so they can be included in guile.

BTW, on the guile side, let me know if you know of SRFI's that are
already implemented so I don't bother with those (I'll probably also
check guile CVS at some point myself)...

OK, sorry for the long silence, but I've been side-tracked by various
other things.  I'd still like to get the srfi's into guile, and that
still requires clearing up the copyright issues, so it looks like
we'll need some paperwork from Dale and Olin.  Are you still up for
this?

If so, I'll see about digging up the relevant details, and
faxing/mailing things wherever appropriate.

Thanks
