Boy oh boy do I find myself wishing Elm had typeclasses

Or at the VERY least that it implemented all the functions for common typeclasses on common types

The Maybe type does have andThen which is really just >>= (it's very janky to rely on convention for that but whatever) but I now have to implement the Alternative functions myself

Surely it's not THAT uncommon to want to take a list of Maybes and return the first Just. Plus Elm boasts about its aggressive dead code elimination so it wouldn't result in bigger apps to add these functions

Bleh

@socks there's stuff like that which used to be in the stdlib. Once it was "simplified" it got moved to various elm-community/TYPE-extra packages.

For instance, the function you're describing is Maybe.Extra.orList: https://package.elm-lang.org/packages/elm-community/maybe-extra/latest/Maybe-Extra#orList

@kae_bytheocean Oh, interesting. Hm, I would expect this stuff to be either in the standard library, or displayed prominently somewhere in the docs

@socks I think they've been full-on "let's make this as simple as possible for newcomers", and the vast majority of the methods in there aren't things newcomers think about.

I see this issue across all software documentation / education, really. I wish you could tell every doc or article your experience level and it decides what collapsed things to expand, etc.

@kae_bytheocean Yeah, I see that. It's not just the docs, Elm is trying a bit too hard to be newbie-friendly in general for my taste. Which is a shame because it also does a lot of things really well
