Damn it! I tried hard. :-)

No. To give a even more concrete application of my example: I'd like
org-contacts to give completion for email addresses or nicknames. If you
have a contact entry like:
- Name: Emmett Brown
- Nickname: doc
- Email address: gigawatt@delorean.com

What I'd like to do is that if the user enters:

     doc<TAB>

is that it can be completed to
   "Emmett Brown <gigawatt@delorean.com>"

But if I return such an item in COLLECTION, it just gets ignored because
"Emmett Brown <gigawatt@delorean.com>" does not match "doc".

This was the point of my example in the my previous email. To just prove
that completion-at-point is being too much picky about which collection
item are valid candidate for completion. I'd like it to just trust what
my function returns. :-)
