[swift-evolution] /*Let it be*/ func() -> @discardable Bool {} /*Rather Than*/ @discardableResult func() -> Bool {}

[Howard Lovatt]

Personally I would prefer all the modified to go on the right, so that the declaration is sorted from most important to least left to right. EG:

Instead of:

    @disguardableResult public async mutating func x() throws -> Bool

I would prefer something like:

    func x() -> Bool @ throws disguardableResult public async mutating

Where @ introduces a list of space separated modifiers. 

That’s why I also prefer:

   let x: Int // Swift

over:

   const int x // C

And moving the where clause to the end of the declaration. 

Unfortunately I am not sure this is practical at this stage.
