String prepend methods

[elland]

Appending is all nice and well, but what about prepending?

Would something like that interest you?

extension String {
    mutating func prepend(_ aString: String) {
        self = aString.appending(self)
    }

    func prepending(_ aString: String) -> String {
        return aString.appending(self)
    }
}

Yeah that seems reasonable. Although is there a mutating append that would make more sense to use than self = aString.appending(self)?

[elland]

@designatednerd what would that look like?

[designatednerd]

Ah OK, trying to come up with an example I see why that wouldn't work - you'd still have to assign aString to self since you'd be mutating aString if you just used aString.append
