You might want to use the ExtLib for this.
You can look at the CVS here :


The code you need :
open ExtLib

let e = input_enum my_file in
let e = Enum.map my_conversion_function e in
List.of_enum e (* will return you the mapped list without any rev done *)
(You'll need the ExtList and the Enum modules for it)

you can use ExtString.enum to get a char Enumeration on your string.
It is more efficient then to use it as an Enum, since you don't create any
data structure to store the chars , but you still can get a list from it by
doing List.of_enum.
