That's also what lisp-complete-symbol uses to tell minibuffer-completion
what is to be completed (more specifically minibuffer-completion
operates on a `field', so I create an overlay with a field property).

That's the kind of UI I was thinking of, yes.  Can you point me to the
relevant code you use for that (especially things like
post-command-hook)?

Yes, rather than a *completions* buffer, we could have tooltip-like
frames show up.  That will need to be chosen by the caller.
