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

I've voted to extend LambdaCase. I prefer thinking that the backward incompatibility problem, in this case, is negligible. Vitaly пт, 17 сент. 2021 г. в 13:25, Simon Peyton Jones via ghc-steering-committee :

Vitaly, Tom

Are you there? I’d love to hear from you about this.

Thanks

Simon

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 https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.google.com%2Fdocument%2Fd%2F1NDXk5kKcLtkqhkSNESAC9jVrBn3yqS_Qe1vacAIKnDs%2Fedit%3Fusp%3Dsharing&data=04%7C01%7Csimonpj%40microsoft.com%7Cb511339e197947e7541d08d9784067da%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637673040277542395%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=jzU6mlExltnKz2q0FPK%2Bm5wTCqXANQJMD7cmJESk85Q%3D&reserved=0. 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.

Thanks

Simon

| 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.
