Hi,
Here is a patch for tex(). It modifies src/mactex.lisp.
I tested it by starting maxima 5.31.0, loading the modified
source file, then running the entire testsuite. This is
with sbcl/linux.
There is a lot of room for improvement, but this is
a good stop-gap.
I could not really see where to put an rtest. But this is
what it does.
(%i2) tex(make_array('fixnum,2));
$$"{Lisp Array: #(0 0)}"$$
instead of
(%i1) tex(make_array('fixnum,2));
$$
Maxima encountered a Lisp error:
The value #(0 0) is not of type SYMBOL.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
HTH,
John
