factorial is very common for *my* use of CAS :

And all? other Computer Algebra System uses ! for factorial.
I feel that ! is the standard function for factorial.
I remember a first play with axiom for an other teacher.
He wants to see a big number, so he tests 123!.
This day he doesn't find axiom as usual as other CAS.
Hmm, does anybody see a reason that ! could not be a special keyword of
SPAD/Aldor that behaves as postfix operator similar to the douple dot
operator ".." in Aldor?
