[plt-scheme] why does the ellipsis not work?
Great, that works fine.
I did try (provide ...), but not (provide-for-syntax ...) and it's clear now
that provide-for-syntax is required. PLT scheme no longer is a small
language and some people regret that. I don't regret it. I understand their
objections, but on the other hand I do like the powerful tools for the
definition new languages. Scribble version of make/doc.txt is coming, I
promise.
Thanks, Jos
