Re: [ghc-steering-committee] RecordDotSyntax: please express a view

I'm very supportive of the proposal overall, I think it would be a major ergonomic improvement to the language. On the question of how to interpret `foo .lbl`, I'm still not entirely convinced that a bare `.lbl` should refer to the selector function. To me the alternative reading of `foo .lbl` being the same as `foo.lbl` is more natural. And I worry (without evidence to be fair) that the proposal's interpretation will be a new, common stumbling block for newcomers to the language. I believe I'm in the minority here, and I can certainly train myself to use the proposal's interpretation, so I won't stand in its way. But it would be really nice if the final implementation could provide a helpful suggestion to try `foo.lbl` instead if type-checking fails!

Dear steering committee

I'm the shepherd for the RecordDotSyntax proposal. https://github.com/ghc-proposals/ghc-proposals/pull/282

I recommend acceptance: https://github.com/ghc-proposals/ghc-proposals/pull/282#issuecomment-5634776...

Please reads the proposal, and as much of the discussion as you feel able, and respond in the next week or two to indicate your views.

Remember: ask technical questions on the Github discussion thread, and use this mailing list for more evaluative discussion of judgement or opinion.

I'd love every member of the committee to express a view. This proposal has attracted a lot of interest.

Thanks

Simon
