Class Functions], which reads:

> So two class functions are equal if and only if their lists of values
are equal, no matter whether they are class functions of the same
character table, of the same group but w.r.t. different class ordering, or
of different groups.

Okay, it seems as though at least you are improving the situation over
what GAP has!
> So this is partly replicated here, except that the patch actually tests
the groups as well as the values.

> If you think it would be better, we can just ask GAP and return the
answer it gives.
