[peppery-idiot]

From my limited knowledge, Rust's type system is quite close to the ML family-- so perhaps F# would be a general-purpose GC'd language equivalent?

I am mainly interested to know how much overhead time is spent appeasing the borrow checker and managing memory that would otherwise free up mental cycles if a GC were available . The async story for Rust also seems confusing (but I hold my hands up and plead ignorance on this count).
