With such a call you haven't change the original "g" function so the
coersion of "g" to "int -> int" doesn't work because it was applied to
the old "g" function.

Try this (after executing your examples of course):

     # let g = coerce g;;
     val g : int -> int = <fun>
     # (g : int -> int) ;;  
     - : int -> int = <fun>

Hope this helps.
Cheers.
