And, BTW, I find the next unsafe behaviour very annoying, especially
when reading text files (while I was still innocent, I got hit):

# int_of_string "9876543210" ;;
- : int = -860875030

# int_of_float 9876543210.0;;
- : int = -860875030

Since OCaml aims to be safe, and since IMO adding an overflow check to
int_of_string & relatives would not be costly (relatively speaking), I
think it should be done. We could add unsafe_int_of_string-like functions
for speed afficionados.
