Looks good to me (but bonus points if you also add a test case for this)

[sebasguts]

@fingolfin Did so, do I get my bonus points ;)?

[fingolfin]

@sebasguts sure, and a pony and a rainbow!

[olexandr-konovalov]

@sebasguts bonus points are awarded only if you will help to fix (50% points if at least identify the reason) of the failure of your newly submitted test when all available packages are loaded: https://travis-ci.org/gap-system/gap-docker-master-testsuite/jobs/316407774

[sebasguts]

Cause QPA has an installation of the function that is installed for arbitrary lists, but does not work on lists with holes. I will provide them a patch.

[fingolfin]

That patch would consist of them removing their PositionsProperty, right? Because it seems to offer nothing beyond what the built-in PositionsProperty does?

Also, unless they release a fixed version quickly, we could raise the rank of our PositionsProperty artificially.

[sebasguts]

Yep, did a PR to remove the functions from QPA.

Update(AK): it is gap-packages/qpa#8
