I disagree - allowing for type inference on the closures will make for a much more pleasant language, whereas requiring type annotations on top level functions makes sense for lots of reasons.

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

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

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).
