8 modules were changed. Only the case "im_func -> !func!" was found.

One occurrence in sage/structure/element.pyx had already been handled in ticket:15983.

Resolved automerge conflict by rebasing on 6.2.beta5.

1 file was already fixed in 6.2.beta5. So only 7 files remain.

I did

git merge u/chapoton/15991 u/wluebbe/ticket/15986 u/wluebbe/ticket/15987

on top of u/wluebbe/ticket/15992 (which is rebased on 6.2.beta5)

Test report:

./sage -t -p --all --long --logfile=logs/ptestlong-alle4.log
...
All tests passed!
