Guile is trying to replace. We could offer them a well-tested,
more-feature-complete extension language, and they could offer us

Hello all,
I have hit a snag in my attempt to add a JIT backend to Guile: I don't
know where to store the JITed code.
There was a discussion of this a few weeks ago in which it was decided
to try to make a simple and quick JIT engine that would be invisible
to Scheme, hoping to eventually make a
first and submit it as a
separate patch for Guile, and then try to add JIT stuff on top of it?

Got it, thanks! Again there's a lot of output, but the most important
bit seems to be here (with some context):

Maybe, but I suspect not. My man page for lseek says that lseek will
fail with ESPIPE if it is called on a socket, and my errno.h defines
ESPIPE to be 29, which is the error we got.
I'll work on a patch for this.

Hello again,
The attached patch fixes the problem for me, and I believe zeroing

Hello all,
I was thinking about how this might be solved. I can see two ways of doing it:
- The nicer way: add a new read function (or a keyword argument to the
current read function) that can tell it to stop without returning
anything if it hits a newline and there's no more input ready on its
