I don't have much of an opinion on this proposal.

I do believe that, in the current state, it doesn't discuss in sufficient detail about whether instances should be considered coherent or not by the compiler. This seems to be the most non-trivial choice in the proposal. I've asked for an addition to that respect on the Github thread.

Hi all,

Ollie Charles’ proposal removes the restrictions placed on HasField instances. Close to my heart, this addresses the problem of creating custom `HasField` instances for record types. I’m in favour of this proposal as it would solve some issues I have encountered, but the floor is open for discussion.

Thanks,

Tom
