Subject: Fast format (was Re: What can I do to help?)
Date: 06 Oct 2002 10:46:31 +0200 [thread overview]

Hello,
I think Guile does not have fast formated output (see simple benchmark).
`simple-format' now implements only basic `format' subset. I think that fast
format could be critical for some type of applications, but simple-format does
not even implement simple number (or string) formating.
