No, to me this discussion is about _grouping_ things, that's why we push for library prefixes.

Just to be clear, "type-grouping" you more or less see the point but "topic-grouping" (e.g regexp, string) not so much?

Okay, but I think we already agree on this? I propose to alias/rename functions where it's "obvious", but as we saw that what is obvious for me is not obvious for everyone, so that's complicated. I think we reached a point where everything proposed was rejected so this is a dead end.
