Comment (by cremona):
Perhaps we need to have some new classes defined, inheriting from the base
class Cusp (which just means an element of {{{P^1(QQ)}}}), which refers to
a specific congruence subgroup. Then some cusp functions, including
equality and Galois action, could be over-ridden in that class.
Doing this properly and well would not be very easy, I think!
