Superficially, I find the syntax very untuitive to read. Most languages opt to use <> for typevariables. Is there a specific reason you chose to deviate from that and use []?

View on HN

I actually can't think of any functional languages that use < > for type variables (I'm sure there's one or two, but it can't be common)

F# does, I think

Depends on what you mean by functional language. I was considering main-stream languages that support some form of functional programming. So Rust, F#, C#, Kotlin, Swift, Typescript, etc

This is only true for C-style languages? Flix uses square brackets, as does Effekt, and Nim, as well as Python. Probably many more I'm missing. Gleam even uses normal parens.

I'm not sure most languages get a vote here.

They can't even represent Fuse's Functor example, i.e.

  f: A -> B, x: F[A]

so maybe they don't get any points for syntax.

Scala and a few others use `[]` (the compiler itself is written in Scala)
