I think that it should be possible to have a Camlp4 syntax extension
to have the equivalent of the C function scanf. I can try to implement
that, if people are interested.

BTW, it is perfectly possible to write printf as a Camlp4 syntax
extension not using the special type "format". In such an implementation,
"printf" is a keyword always followed by a string. Camlp4 analyses the
string and generates calls to print_string, print_int, and so on. The
result is normally typed by OCaml.
