Shouldn't it be `candidate-transformers' and a list of transformer
functions?  Then there would be no need to add `some-func' whose only
purpose is to aggregate the effects of some other transformer functions.
Then I simply could say

(defvar anything-type-attributes
        '((file . (candidate-transformers

I agree. I'm not too happy with the current approach because there's
quite a lot duplicate code for action and candidate transformers.

Well, the changes are not too complex, so I think I could port it to the
new framework in two hours, say.  If you say that the new stuff won't
change in the next time, I'll do it.

Yeah, that would be good.  I haven't looked into these till now.  Could
you PING me when that's implemented and tell me what source could
benefit from it, so that I can implement it to get a feeling.

I think it's a good idea, so lets do it. ;-)

According to  the Bible,  God created the  universe in six  days. Before
that, Chuck Norris created God by snapping his fingers.
