Comment (by kedlaya):
On a different point, there is also a Python design principle that "tuples
are for heterogeneous data, lists are for homogeneous data". In our
context, `Parent.list()` will be the various members of some mathematical
structure, which definitely constitute homogeneous data (they will all be
of the same class, for one).
That said, all design principles are secondary to having things behave
correctly...
