Comment (by tscrim):

 Hey Volker,

 I was talking about the modules `libs.gap.*`, in particular the one which
 triggers the rest is `libs.gap.element`. However by lazily importing this,
 I ended up getting errors, so I don't think we can get around this (plus
 it's not really a big import or a significant slowdown to startup time).
 I'd guess this is related to #14357, but it's definitely not worth holding
 this ticket up.

 Anyways, I've uploaded a small reviewer patch which does some minor to
 trivial docstring changes to methods that are being moved around by this
 patch. If you're happy with my tweaks, I think we can set this to positive
 review.

 Best,[[BR]]
 Travis
