The people proposing this can correct me if I'm wrong but my
understanding of their motivation is not to remove record syntax or
immediately to replace it, but to make it easier to experiment with
replacements by making the existing labelled fields syntax a modular
part of the language that can be turned on or off (like the FFI).
I'm not sure that I agree that it's the best approach but it is one idea
to try and break the current impasse. It seems currently we cannot
experiment with new record systems because they inevitably clash with
the current labelled fields and thus nothing changes.
