Hello Hugo,

Just do:

 # let m : int IntMap.t = IntMap.empty;;

The " : int IntMap.t" type annotation restricts the default "'a
IntMap.t" of IntMap.empty.

> # let m = IntMap.add 1 "42" m;;

Then:

 # let m = IntMap.add 1 "42" m;;
Characters 26-27:
  let m = IntMap.add 1 "42" m;;
                            ^
This expression has type int IntMap.t but is here used with type
  string IntMap.t


Best regards,
david
