Not so in OCaml, where + isn't even polymorphic to int64, so I have to
break out manual calls to Int64.XXX methods. Here, I went with a
helper variable 'fudge'.
No implicit type conversions in OCaml! (as a deliberate choice)
You don't need to the parens around Int64.add since function
application always binds tightest.
You could have written this if you'd wanted:
let (+^) = Int64.add
...
assert (cr3 = cr2 +^ fudge)
Custom operators always have the same precedence as the normal
operator with the same first character.
Or in recent OCaml versions:
assert Int64.(cr3 = cr2 + fudge)
Rich.
