One the struggles I've faced since working on the open source version of
AXIOM is getting free Lisp systems work flawlessly everywhere a C++
is available. Working on AXIOM only has strengthen my views on Lisp
(including Common Lisp), but in ways Lisp enthusiasts would not welcome...
I would be interested in a portable, open source, efficient Lisp system
that integrates pretty well C++ -- my primary interest in this is for OpenAxiom
which is already a mixture of Spad, C++, and Lisp.
