I do not understand your point. This was a stripped down problem related to a method of displaying results in Maxima, method which is used by factor() and I intended to use in one of my functions. I am a professional mathematician and I don't know Lisp but I use Maxima and like it.
With the provided code I get an error message in Maxima:
Maxima encountered a Lisp error: Error in MACSYMA-TOP-LEVEL [or a callee]: MACSYMA-TOP-LEVEL [or a callee] requires less than two arguments.
