It's interesting to see a bunch of assemblers in CL. I wrote one
recently for the m68k, with an accompanying linker for producing Atari
ST binaries. I was going to retarget it for the ARM sometime, but your
design sounds more interesting (I was going for an assembler with more
convenientional syntax, that can break out into lisp for macros).

I'm hoping to release mine soon, once I get the time to clean up a few
things (better errors and warnings). I'd definitely like to see the
others, as well.

Cheers.
