[Caml-list] '_a out of nowhere? (list.reverse)

["Seth J. Fogarty" <sfogarty@students.uiuc.edu>]

# let cons x y = x::y
# and flip f x y = f y x ;;
val cons : 'a -> 'a list -> 'a list = <fun>
val flip : ('a -> 'b -> 'c) -> 'b -> 'a -> 'c = <fun>
# let reverse = List.fold_left (flip cons) [];;
val reverse : '_a list -> '_a list = <fun>
# reverse [1;2;3];;
- : int list = [3; 2; 1]
# reverse ['a';'b';'c'];;
This expression has type char but is here used with type int

I've encountered similar things with references, but never with something as
basic as a fold_left. Can someone tell me why this is happening? This, to me,
is very wrong behavior. This is on Debian's OCaml 3.07.
