This function approx-alike has a bug: (The testing code uses approx-alike to test for equality.)
(%i1) ?approx\-alike(a[1],a(1));
(%o1) true
I filed a report (https://sourceforge.net/p/maxima/bugs/2511/). Since this bug has been with us for years, I don't think
it's a deal breaker for 5.29. With my proposed fix, the test suite runs OK.
The diff for my proposed fix was automagically formatted as a bullet list :( Apparently, I need to read the "formatting help" document :(
Also, it's necessary to read a bug report to see who submitted it--previously, that information was listed in the summary :( Maybe I'm just grumpy :(
