Do I understand correctly that the difference is between, for example, expanding command names (completing), and choosing an emoji in a list (selecting)?Yeah, I don't get it either. If I'm completing a command name, I can also say that I'm selecting a command name from all available command names. Or when I'm completing a file name, I'm selecting a file from all the files on my system.
I agree with both of you. I also don't see a significant difference between `completing-read' and a potential `selecting-read'. However, the `completing-read' API could benefit from a few small improvements as I proposed in my other mail. Given all the experience gained one may consider introducing a `completing-read2' which incorporates all the lessons learned and offers an API, which is a bit easier to use. But maybe the costs would outweigh the benefits and applying incremental improvements is actually the better approach, see for example the recently added `affixation-function'.
