Re: [Haskell-cafe] Syntax proposal for "reverse apply"/"pipeline apply" (flip ($))

This was brought up again in one of these very long threads in the cafe that have happened 2-3 times now. Last time when this came up in October, I offered to submit it to the core libraries committee for review as the previous time it had come up it was fairly contentious, and I opted to abstain from expressing an opinion for or against due to my role in the previous proposal. I submitted it to core-libraries-committee@haskell.org. They reviewed it, and came down 4 in favor, 2 not commenting, after a bit of a bikeshedding discussion the existing name was picked, and the scope was declared limited to just putting it in Data.Function, and not including it in Prelude. We decided to wait until 7.10 to put it in since at the time 7.8 was happening "any day now". Now it has happened, so when the topic popped up again it was just a matter of implementing an existing resoution. I do, however, agree the discussion of submitting it should have happened on the libraries mailing list. -Edward Kmett -Edward On Fri, Apr 18, 2014 at 10:56 AM, Carter Schonwald < carter.schonwald@gmail.com> wrote:

Indeed! (And while it looks like a Alex and Edward voted, not sure who else did :-) )

I didn't even notice that this discussion was on haskell-cafe. Ideally such discussions should be on libraries@, as people who only want to read about more important stuff can subscribe to only that list.

There's a concensus email? Im pretty sure most folks don't check cafe threads for rfcs :-)

So far our decision has been "no". You are mistaken. Please see Edward's email.

«Consensus was achieved to add it as an infixl 1 & operator to Data.Function, but not to Prelude,so we just need to put in the patch and you'll see it in GHC 7.10.»

A patch has been provided and a GHC ticket has been opened.

My apologies. I must have glanced over the details since I've seen '&' and '|>' proposed before on this list. Please link to the consensus email in the GHC ticket (I saw one of them got closed because it didn't.)
