[Caml-list] Infix operator

[Alexsandro Soares]

Hi all,
   Is there any way to define infix operators in
OCaml?

   Cheers,
   Alex

Yes. This is described in the excellent book "Developing applications with 
objective Caml" in the "Functional core of Objective CAML" chapter, on page 
25 under the heading "Declaration of infix functions". This book is freely 
available in electronic form here:

http://caml.inria.fr/oreilly-book/html/index.html

Basically, use only symbols in infix function names and define the function 
using the syntax:

# let ( ++ ) c1 c2 = (fst c1)+(fst c2), (snd c1)+(snd c2);;
val ( ++ ) : int * int -> int * int -> int * int = <fun>
# (2, 3) ++ (3, 4);;
- : int * int = (5, 7)

Cheers,
Jon.

The French version is published by O'Reilly France, but the English 
translation hasn't been published.  I recently asked the head office why 
they haven't published anything in English about functional languages, 
and they said it was because books on functional languages didn't sell 
very well.
