> allowing for type inference on the closures

You can still have your type inference without forcing the unnecessary requirement that local functions be `fn` while top functions be `func`.

I agree with this, I'm designing a similar language and have gone with this approach. Same syntax for all functions, but top-level functions require explicit type annotations (purely for documentation/sanity more so than a technical requirement).

agreed, but there's still differentiation in syntax, and I was responding to someone asking for no differentiation.
