Re: [ghc-steering-committee] Proposal #302: Multiway lambda: new extension or not?

We should give our users the option to keep using LambdaCase without enabling LambdaCases. I, for one, do not like the flavor we ended up choosing, so I’d keep using LambdaCase alone in my programs. I imagine other users might want to do so as well. - Vlad

Hi,

on the multiway-lambda story, we have voted to add \cases alongside \case. But one open question is still: Do we (1) add -XLambdaCases (which would imply -XLambdaCase) or (2) simply expand the meaning of -XLambdaCase.

On the Github thread at https://github.com/ghc-proposals/ghc-proposals/pull/302#issuecomment-8950800... we see that I lean towards (1), but SPJ leands towards (2).

It doesn’t matter that much, but we need to make a decision. Can I please get some opinions from the rest of the committee on this point?

Cheers, Joachim
