This doesn’t work unless you’re willing to break consistency with function type
syntax, or if you’re willing to make function [type/decl] syntax ambiguous.
How would you express this, for example?
let x : (_ a : Int) throws -> (_ b: Float) throws -> Double
it would be ambiguous to move the ‘throws’ keyword to the end of the function
type, because you'd get:
let x : (_ a : Int) -> (_ b: Float) -> Double throws throws
