To balance my (a little trolling post), I must say that racket community is

For my part, you're welcome. :)
I am interested in math, and I follow for example maxima, julia and R.
It should be wonderful if the new math library could be integrated in any way
with the symbolical capabilities of maxima. In a recent post there was a
question or problem about the GPL license. I don't know if that is a real
obstacle, but I think that union is a power tool. Perhaps some form of union
between maxima and the library in typed racket would be wonderful.
It could be wonderful. I love using Maxima, and I find it to be stable,
consistent, and very useful.
Licensing is a real obstacle, though.
I don't know whether Maxima can be used as a library. If it can, because
it's GPL, we can't include Racket bindings to it in our decidedly LGPL
standard library. If anybody does distribute Racket bindings, they must
be GPL, and any project that uses those bindings must also be GPL.
One option is to talk to Maxima by squirting text through pipes, but
that sort of thing has always been brittle. I wouldn't try it, and I
don't think it would pass code review with the other Racket devs.
Since starting the math library, licensing has been a constant thorn in
my side. The projects that I would love to just translate
proven-to-be-stable numerical code from generally fall into four camps:
1. Closed-source.
2. GPL, as backlash against #1. The Gnu Scientific Library (GSL) is
very vocally in this camp.
3. GPL, because they wanted to reuse code from or link to #2 projects,
usually the GSL. I think R is in this camp.
4. Don't care about licensing, so terms are unclear.
I get the impression that licensing for mathematical code in general,
not just numerical code, is messy and annoying.
So maybe this is an opportunity. If the only option for getting good
math support with liberal licensing terms is Racket, we could see a lot
more people using Racket. I've been trying to outdo R in particular in
plotting, distributions, and statistical functions. We're not yet to
where (require math plot) is an R substitute, but we should be close -
perhaps with a few extra Planet2 packages - in 1-2 years.
I think we have the expertise around here to do computer algebra the
right way. Any takers?
