Motivational example:
var urlString = self.urlString
if urlString.hasPrefix("//") {
urlString = "http:" + urlString // urlString needs to be typed twice
}
While there is currently an easy way to append string using +=, there is no shortcut for prefixing a string. What I propose is adding a =+ operator for prefixing the string:
urlString =+ "http:"
Would anyone else find it useful?
