Subject: [Caml-list] default values for record field definitions
Hi All,

It may well be that I'm not in the first hundred of those who proposed
this, if so - sorry :-).

Why not to introduce a syntax for default values of record fields:

type rec1 = { attr1: type1 = val1; attr2: type2; attr3: type3 = val3 }

It this case constructions of the form

let x = { attr2 = val2 } are possible, with other fields filled by val1,
val3.

Can it be done via camlp4?

Alexander
