Comment:
These are definite improvements, well implemented, and doctests pass.
Just one remark:
The eventuality envisaged in the comment at line 95 of the
patched `class_group.py` (which should be referring to ideal classes
rather ideals) ought to have its own doctest, such as:
{{{
sage: K.<a> = QuadraticField(-23)
sage: L.<b> = K.extension(x^2 - 2)
sage: CK = K.class_group()
sage: CL = L.class_group()
sage: [CL(I).list() for I in CK]
[[0], [2], [4]]
}}}
