Some months ago I sent a patch to Rails proposing an Array#to_proc the
way we already have a Symbol#to_proc:
http://rails.lighthouseapp.com/projects/8994/tickets/1253-arrayto_proc
As pointed on the discussion, we only had some few cases (on Rails) to
add this method, but what do you guys think about it on the language
itself, would be useful or it does not help anyway?

Thanks.
