Example of using [] for type params and .() for indexing: brson.github.io/archaea/foreac

I don't think that _exactly_ would have survived but since we use .0 etc for tuple access I think arrays coulda been the same.

Oh yeah, I think `()` for indexing like in Scala is fine too.

I love that collection access in scala looks like a function call like that.

Me too :) I like Scala a lot because of how it handled `apply` and `update` (and even more because of how library authors know not to make a trait govern syntax sugar)

how does Scala solve for making indexable user collections anyways?

I think the call operator is overloadable?

oh god

Everything is overloadble.

In Scala? Yeah, you can define any operator you want. Thankfully unlike C++ there's an emphasis on purity and clarity (and unclear operators often get deprecated, like /: and :\ [nobody had any clue what those did])

and

Yeah, as an outsider things seem a bit nicer in Scala land since the move away from libraries like ScalaZ (which used far more operators than healthy), towards Cats which seems more restrained and careful in its choices of operators…
