Comment:
It should be possible to define a cpp class storing the two pointers (as
the current C struct) with an additional mehod calling the restore method
through the two pointers in sage/libs/ntl/whatever.pxd or .h and
implement it directly in an additional sage/libs/ntl/whatever.cpp.
One would have to include the NTL directly, and maybe hack through the
hackish name mangling currently done in Sage (I presume the NTL wrapper
was written before Pyrex/Cython correctly supported C++).
Not sure it is worth the trouble doing that in Sage.
But this is surely worth a mail to Shoup in case he agrees to add a new
method to ZZ_pEContext restoring both the modulus and the characteristic.
