It doesn't work for cyrillic-translit, for example, so I'd guess it
requires core changes to the quail code.  The other issue is that TAB
has a meaning while you're typing, so if you type /'TAB in
cyrillic-translit, you'd get two completion candidates (/' and /'')
instead of ’ followed by the TAB character.  I think that's less useful
to the user, since hitting TAB is so common in all Emacs modes.

Regardless I agree that it's useful to do this, because so many quail
input methods have more mappings than an user can easily remember.

Maybe it could be bound to M-TAB.  I don't know if it can be a callable
function, because it needs to be incorporated into the quail keystroke

I also think Unicode characters in particular can use an
`ucs-insert-by-name' function instead of or in addition to an input
method, because it's such a useful operation and there are so many of
them.  The user wouldn't have to customize anything or call anything
complex, either, he'd just call that function and work with the
completion candidate list in the standard Emacs way--no special
keystrokes.  Input methods are a bit harder to customize and use (but of
course, they have many advantages over functions).
