I'm pretty sure the stuff in integer_list.py is not deprecated yet as it's still needed.

revert remove of iterator() and list()

[Jeroen Demeyer]

I know I'm being pedantic here...

Explicitly calling Partition._repr_(self, compact=False) hasn't been deprecated so I guess the argument cannot be removed, it should just be totally ignored but not disallowed.

And RootSystem(['A',2]).weight_lattice().pi isn't deprecated either...

According to the comment it somehow is deprecated. But I can revert this change.

Do you want me to deprecate the argument?

What I meant is that the deprecation warning is commented out in the code for reasons which are not entirely clear to me. I think you should just uncomment that deprecation warning (with ticket number #16933).

Perhaps replace the argument with def _repr(self, compact=None): and then you can do in the code

if compact is not None:

Adding a deprecation warning to pi() leads to several failing doctests because of the @lazy_attribute. Removing @lazy_attribute also doesn't help.

Since there is a warning about the deprecation of pi() in documentation for more than 2 years now (see #6588), we should simply remove pi().
