Hey, why, wait, what happens if you create a zeta such that
zeta.multiplicative_order() doesn't work?!
{{{
sage: a = CDF(CyclotomicField(5).0)
sage: G = DirichletGroup(11, base_ring=a.parent(), zeta=a, zeta_order=5)
sage: G
Group of Dirichlet characters of modulus 11 over Complex Double Field
sage: G.0
[0.309016994375 + 0.951056516295*I]
sage: G.0(2)
0.309016994375 + 0.951056516295*I
}}}
Please revert getting rid of zeta_order and make that part of another
ticket, keeping in mind that you can't exactly do that, since it is
important. The above doctest should be put in that ticket since this
problem wouldn't have happened if I had included the above test.
