I think agree with this, but it should work with Non-GUI Emacs, too right?
In a TUI Emacs, there have been these nice pop-up menus for a while.  At first
sight the display infrastructure being used there seems suitable for showing
completions, so I wonder if that infrastructure couldn't be refactored
then reused
for a completion popup in core.
