Throwing functions

throwing.swift

// Is there a reason to why the `throws` keyword is at this position:
func send() throws -> String {}

// Instead of…
throwing func send() -> String {}

// Like `mutating` is declared:
mutating func send() -> String {}

// To be consistant, throwing should be at the start of the declaration, right? 
// Am I missing a message in the mailing list about that, or is there another reason?
