Maybe flamebait .. see below.
The decision was made to use Python ( 1?) for whatever reasons
were articulated at the time.
Apparently there is an issue with backward compatibility
requiring rewriting of code. I don't know this first hand.
A more-or-less formal language definition
for the language, -- such that any correct program
conforming to that standard is guaranteed to perform
in essentially the same way in all (future) implementations--
seems to be missing.
For some purposes, choosing to use a language without such a standard
definition is problematical.
If there is no standard ("a reference manual" is probably not
good enough. A reference implementation -- eh, maybe ..)
then that counts against using that language.
If all programs written in Python have to be re-examined and
maybe rewritten every few years, that seems like a real bummer.
Is that really the case? Or is it just Sage? What about all that
code written by Google?
If I misunderstand, then respond on SageFlame :)
Common Lisp was standardized in 1994 or so. True, there are
some parts of computing relating to WWW and GUI and such
that are not included, and that's sometimes a problem. But
there are 50-year-old programs in Maxima.
I think that if someone proposed a "new" CL standard, it would
have to be backward compatible.
