Wouldn't it be better to go to a virtual machine + general optimizing
phase compiler core + multiple frontends model? These other languages are
nice and all, but how well do they support numerical computation? And how
much cruft would be generated (if you choose Scheme, I would think you're
most of the core code (what's written in C++) would still be in C++ or C,
but with a load of Guile hooks in them. Is that going to improve the
developer situation or worsen it?
Personally, the only time I care about Matlab compatibility is when
I see some useful code someone else has written in Matlab and want to use
it with as little pain as possible. I'd just as soon have a better
language interface for myself, though. Something with continuations and
run-time macro expansion and a good object system and (drool obscures
further feature lust).
Plus it would provide a clean separation of concerns so I don't have
to dig to the deep core when I only need something superficial (replace
"I" with "J Random Coder" if you like). While there's a lot to be
grateful for with Octave, there are problems as well. And source
documentation has got to be a big one for expanding it developer
base. Forcing this kind of separation would at least require
documentation of the interface. And it's been my experience as a reader
of software that the most flexible/cleanest designs are those that read as
interpreters (of their data, not that they have lexers and parsers).
Take these comments for what they're worth, as I don't have the time
or expertise to help with this. I'm only offering them as someone who
reads much more code than he writes, and has an opinion on what's easier
to read and thus work on. YMMV.
