Thanks for your feedback. I had overlooked the fact that `aptitude
versions` behaves in a special way.
However `apt list` does not behave as `aptitude search` either on my
system:
$ apt list '?any-version(~i~Aexperimental)'|wc
297 1430 20645
$ aptitude search '?any-version(~i~Aexperimental)'|wc
8 65 385
Am I still missing something?
