An alternative front end for Haskell?
> do you really have to understand language extensions?
You do when your code doesn't compile and you're trying to figure out what the error message means, or when the library you want to use makes heavy use of it for even basic functionality.
> These days one just enables GHC2021
My experience was pre-GHC2021. I basically had to enable at a minimum 5-6 language extensions in every single file.
> Mostly they're just about removing unnecessary restrictions from the older standard.
Yeah, those ones are usually fine. I have zero objection to things like FlexibleInstances or DeriveFoldable.
> Could you give an example?
I believe I was trying to implement Central Authentication Service using Servant. However, that required returning a custom HTTP status code. There has been an open Github issue for this since 2017, but it seems to require basically rewriting the entire framework: https://github.com/haskell-servant/servant/issues/732
Looking back at it now Servant does have "ServerError", but that basically requires giving up all the advantages Servant claims to have and I believe it was not a viable option at the time. Looking at the timeline I was probably also on Servant 0.15, and there seems to have been a rewrite since then.
I vaguely recall running into a similar issue trying to interact with a database, but I can't remember the details of that.

Monthly Hask Anything (November 2022)
If you don't like this style, the usual alternative is to change mkDualAuthHandler to take two additional arguments, Proxy tag0 and Proxy tag1 (as e.g. lots of Servant functions do, for historical reasons).

Introduction to Doctests in Haskell
And what about the cabal repl --with-compiler=doctest, which was added recently, in doctest v0.20? I recently submitted a PR for Servant to use this in place of GHC environment files, because it seems less finicky to me. Was this a bad idea?

Generate Typescript from Servant API
I asked a somewhat relevant question recently. Maybe you'll find this discussion somewhat helpful: https://github.com/haskell-servant/servant/issues/1547; two packages were talked about. One of the folks from Well Typed replied, and said they tried it recently (and worked fine).
