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?

Kind of like in Rust, with the `Fn` traits (which are not yet overloadable in stable Rust due to the lack of variadic type params)

I'm gonna be honest with you if we have anything but arity overloading I am rioting.

sorry, not sure I follow… is this a Prolog reference? Was more talking:
trait Fn<Input, ..., Output> { ... }
or:
trait Fn<(Input, ...), Output> { ... }
Seems like a tricky thing to figure out though, so I'm not holding my breath it will be available soon…

it is common in many languages to notate functions as
name/arity
to disambiguate between the functions with the same name but different arity. Prolog, yes, but also Erlang and Elixir.

Also Mercury! 😊 I think the notation comes from Prolog, Elixir by way of Erlang.

Was more just confused about the joke I guess, sorry!
