Comment(by kcrisman):

 But I don't think we want ALL such functions (if you are referring to all
 functions in rings/arith.py).  I don't think we have a keyword otherwise,
 and it certainly isn't worth the time to do four_squares or primitive_root
 (which just gives the smallest one) as a symbolic function before we have
 even implemented some of these other functions.  Anyway, I'll change the
 summary again to make my preference clear :)

 Interestingly, these three functions all give different errors upon giving
 them 'x' as an argument.  That's probably irrelevant, but still fun to
 point out.
