Maybe you can say something about your larger goal here. If the goal
is to process del(something) expressions somehow, there are ways to
get Maxima to handle a lot of the details for you, via the pattern
matching functions (tellsimp, tellsimpafter, defrule, defmatch). If
you find yourself writing code which tests the operator and perhaps
the arguments as well to check for different conditions, the code can
probably be simplified and extended by using pattern matching
functions.

best,
