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

Hi, accepted, with using -XLambdaCase. Thanks all! Cheers, Joachim Am Samstag, dem 18.09.2021 um 12:40 +0300 schrieb Vitaly Bragilevsky:

I've voted to extend LambdaCase. I prefer thinking that the backward incompatibility problem, in this case, is negligible.

Vitaly, Tom Are you there?  I’d love to hear from you about this. Thanks Simon   PS: I am leaving Microsoft at the end of November 2021, at which pointsimonpj@microsoft.com will cease to work.  Usesimon.peytonjones@gmail.com instead.  (For now, it just forwards to simonpj@microsoft.com.)   From: Simon Peyton Jones Sent: 15 September 2021 13:00 To: ghc-steering-committee@haskell.org Cc: Simon Peyton Jones Subject: RE: [ghc-steering-committee] Proposal #302: Multiway lambda: new extension or not?   Vitaly, Eric, Tom, Alejandro As Joachim says, we need to make a decision on the LambdaCase flag issue.  It’s a judgement call, so let’s just vote. Here is the voting sheet.  I have filled in votes from Simon, myself, Joacim, Richard, Vlad.  But four of us (in the to: line) have not expressed an opinion. Could you do so please, in the next day or two?  It should take you 5 minutes.
