rio-orphans VS ghc-proposals

https://github.com/commercialhaskell/rio#language-extensions which is cited as an example in simplehaskell's page on recommendations.

> Can we move to a better standard lib? Here Snoyman has put forward a great effort by releasing his classy-prelude, but iirc he also stopped using it.

He mentioned https://github.com/commercialhaskell/rio in the 1st article, it's interesting, I wasn't aware of it. (I am using classy-prelude but I might try it out.)

It's worth mentioning that Snoyman's "Boring Haskell" is actually a fairly moderate position: if you look at his suggested list of language extensions, it's pretty broad (and fairly reasonable in my view).

via ByteString was recommended by Snoyman in the post Beware of readFile (referenced in the Haskell: The Bad Parts, part 1 too). But this has got a disadvantage compared to Data.Text.IO combined with hSetEncoding. This might be a good time to update Beware of readFile, u/snoyberg.

Additionally, while this proposal is focused on the simple implementation and so in the current proposal or patterns do not bind any variables as per #522, if we do get settled on syntax and then later wish to expand to allow binding variables as in #43, then the syntax is again clean and discoverable.

Yeah, a relatively natural thing would be to be able to opt-in to having the HasField instances be available in all contexts. The (not yet implemented, but accepted) "Modifiers" GHC proposal might be nice for that.

The local modules proposal imo is excellent as-is.

Why would you drop TypeFamilies? It seems fairly popular, given that it was just one vote short of getting added to GHC2021. Do you consider it a less-ideal compromise, that is subsumed by your second proposal (Core with GRTT)?

as syntax is contentious a topic as ever, David (the main proposal author) and I would like to invite you to give your input on https://github.com/ghc-proposals/ghc-proposals/pull/585, where we propose to change the syntax of the accepted proposal #522 introducing Or patterns. In particular, we'd like to know

This looks great, congratulations on completing it! I assume you didn’t get an opportunity to evaluate the delimited continuations based eff library? It would’ve been nice to see Cont included as one of the effects covered, though perhaps not available in all the systems you looked at? Maybe some future work.

I do hope qualified exports are available someday: https://github.com/ghc-proposals/ghc-proposals/pull/283

Right. Being able to disable "custom type warnings" at use sites was part of an earlier proposal (https://github.com/ghc-proposals/ghc-proposals/pull/454) but it ended up being shelved.
