This might be the reason why it is not used for the implementation of the

Conjugate-simp doesn't use opers-apply because I didn't know about
opers-apply
when I wrote conjugate.lisp. The same is true for the trig reflection
rules. Actually for the reflection rules, I only revised the old code (that
also did not use opers-apply).

If I were to write conjugate.lisp over, likely I wouldn't use opers-apply.
It seems to me that opers-apply sorts through many possibilities; also, I'm
not fond of distributing the work of simple tasks over multiple
files and functions.

Maxima places a great deal of data on property lists; for efficiency,
I have wondered if some of this should be placed into hash tables.
Try :lisp(symbol-plist 'mplus). Yikes! What is all this stuff (references
to nset, for example).
