Hmm. It seems too tricky. How about this more formed idea.
Vim can check type of returned value from completefunc, so vim should
accept not only array but also dictionary. For array value, vim use it
as same as currently. For dictionary value, vim behaves some parsing on
it.
For example, 'refresh' means as you wrote, 'candidates' has array of
completion candidates.
let l = list-with-complete-items
return { 'refresh': 'always', 'candidates': l }
Besides it is extensible for future use.
