Hi Camille,

I know about the INLINE declaration.  However, it says there that "no
conforming implementation is required to perform inline expansion of
user-defined functions" and it seemed to me that LW didn't always do
what I wanted.  But after writing my email I tried again with DECLAIM
and it suddenly (...) worked.  (In other words, I probably had
confused myself somehow.)

Still, it'd be interesting to know what DEFUN-AND-INLINE is good for.

Thanks,
Edi.
