I must admit that I do not understand what you really mean. Do
you mean that at conceptual level we should use different abstract
machine? Or maybe you mean literally re-targeting Spad compiler?
I would say that at conceptual level I abandoned Lisp long ago
(or rather Lisp was never my conceptual model) -- I am not sure
if my model is clear enough to present to others, but it is
definitely different from Lisp. At coding level I am trying
to reduce/localize dependence on Lisp, but there is still
substantial work to do -- ATM dropping Lisp is not practical.
