Still, there are ones that are well-recognized as standard, a common
basis for software libraries, shared development environments, etc.
Others have been found lacking by refereed published articles
and have failed to gain adherents outside the originators. (Distrust
of significance arithmetic ala Mathematica is not a personal
subjective opinion only.).

I don't know what other tools you are considering. Certainly symbolic
computing goes places that numerical programs do not go (easily). That
doesn't really justify support for eccentric arithmetic.  If you
say that eccentric arithmetic is praiseworthy, I find that peculiar.

This is a non-sequitur.


Your shoelace is untied and you should tie it.
No, because elsewhere there are some untied shoelaces.

Maybe, but is "pretty good"  the goal, and the occasional identified
errors be ignored?

Please, too much.

I've never used SPICE,though numbers of people have made academic
careers (at Berkeley) about it, and some people have made a great
deal of money directly or indirectly from it.

My impression is that the authors and implementers of SPICE
were substantially under-educated with respect to computer science
language design principles.  Electrical engineers writing user
interfaces, initially in FORTRAN --> prospects look dim.
Wolfram got some excellent people doing UI early on.
