Well, I agree that OpenAxiom code _looks_ better. You say
that 'attempting to decode how FriCAS actually ends up
producing the output' boggles your mind. However, have you
tried to understand what OpenAxiom is doing?
FYI FriCAS code was rewritten this summer and what it is
doing now is much simpler (and faster) than original version.
Actually original did crazy things and the only reason I
find for doing such things is that previous authors did
not fully understand what it is doing. AFAICS OpenAxiom
still contains at least part of original craziness.
