I think it should be easy to provide this for a few data types (matrix,
string, maybe list), but I think the conversion from a Lisp sexp to an
ELisp sexp will need a lot of assumptions. E.g. how to convert the
Maxima list:

[[a,b],[c,d,[e,f]]]

Or maybe such cases are not important?

Also, what would we do with an arbitrary mathematical expression? Return
a printed representation?

Thanks.

I have used Calc, but never really got the hang of it.

Developing a working session for maxima would make it more feasible to
use it directly in text, as you are using Calc.
