This is too abstract a question.

The original issue was not about Calc, it was about a standalone math
library.  For that, we should first define the scope.  One possibility
is to expose to Lisp everything in a typical libm, but is that needed?
Another possibility is to provide a statistical library (average,
median, standard deviation, t-Student, F-test, chi-square, etc.) --
but do we need this?  Etc. etc. -- "math library" can be interpreted
in many different ways.

If we are now talking about improving Calc, someone who knows Calc
well should describe what is needed, and we can then discuss that in
detail.
