Thanks, have read the paper, however also saw the paper by Simon
Peyton-Jones and
Mark Jones on Lightweight Extensible Records for Haskell, which I think
Simon refered
to in an earlier post... would it not be better to have this instead?

But I just wonder : why not keeping both records systems (Haskell 98 and
extensible) with their own syntax, introducing for example [{..}] for
extensible records for example. This would resolve
Hello, is there something like extensible records in ghc?
Are you wanting something like Hugs' T-Rex or did you have something
else in mind?
Hello,
For what I understand of T-Rex it is what I wait.
I need something that can allow to use records without declaring their
type first and that

Which, presumably, is why he wants T-Rex which gives strong typing and
extensible records and comes from the same great source (MP Jones)
names some fields that should have the same name.
