Yes, that's actually the only real difference I see between records and 
tuples. I have the feeling that every other difference is just syntactic 
sugar.

Now, unless I'm mistaken, OCaml's design is mostly towards structural 
typing. Usually, when one wants nominal typing, one resorts to abstract 
types safely hidden in modules. From this point of view, nominal typing 
of records is therefore somewhat surprising.

Am I getting something wrong ?

Cheers,
 David
