Comment (by SimonKing):
Unfortunately, I get
{{{
sage -t "devel/sage-main/sage/rings/number_field/number_field_ideal.py"
[21.9 s]
----------------------------------------------------------------------
All tests passed!
Total time for all tests: 22.0 seconds
}}}
So, what happened here?
In any case, I think the example of collectable pushout should be included
in the documentation, combined with a warning to keep a pointer to the
pushout (or avoid cross-parent arithmetic altogether), if speed matters.
I could write that. But to what location? Logically, it belongs to
sage.structure.coerce, but nobody would read that. It might better be in a
more general tutorial. What do you suggest?
