Subject: [Caml-list] Accessing record fields

Hello.

OCaml offers at least two ways of accessing a record field: using the
dot notation, and doing pattern matching.

Does one of them deliver better performance than the other?

This may be relevant when a field is accessed multiple times.

For instance:

   type trec = { a : int; mutable b: int }

   let f {a;b} = a * a + b

   let g r = r.a * r.a + r.b

Which one would be preferred in this case: f or g?
