I'd prefer not to have a program-global modulus. Remember that we're
also trying to put threading into TR2.
Alternatives:
- Optional modulus argument to certain functions. This seems to be the
approach that Mathematica chooses.
- Maybe a reference to the modulus in the constructor.
[ Yes, I know that NTL uses the static modulus approach. Still, my gut
feeling tells me this is suboptimal. ]
BTW, it seems strange that modular arithmetic should restricted to
unsigned integers.
