Intention:
Re-use a reference.
Actual Results:
The ref naming scheme needs improvements so that humans can remember which ref name they want to re-use, especially if they are using the wikitext editor, where they will not have any of the possible hints that VisualEditor may provide.
Expected Results:
A system that is "xxx:0", where "xxx" is text simply copied out from the beginning of the named ref would be an improvement. We can assume that anything inside the ref is in a language that the editor is capable of coping with. We can exclude the names of templates and their parameters, as well as "http" (otherwise, bare URLs in refs will produce a lot of equally unfriendly <ref name=htt:n> names).
