Subject: surprising type error with labels
Date: Thu, 19 Jun 2008 14:38:38 -0700 [thread overview]
Message-ID: <c7e4e9f0806191438j9f7a742x6989fc2d7b192a0f@mail.gmail.com> (raw)
Hi list,
Why does
ListLabels.find (fun _ -> true) [];;
produce
Characters 16-31:
ListLabels.find (fun _ -> true) [];;
^^^^^^^^^^^^^^^
This expression should not be a function, the expected type is
('a -> 'b) list
I thought the rule was that "if an application is total, labels may be
omitted." (4.1 in the manual). (I was trying to do module List =
ListLabels at the top of a file.) Thanks,
Jake
