init(set name:String, set score:Int) { }<br>

set would be a fourth parameter modifier alongside let, var, and inout - only valid on initializers (not as useful and likely confusing in other contexts). The local name has to match a parameter on the type. Like let/var (but unlike inout) usage of ‘set’ on a initializer parameter does not affect the caller or prototype conformance.<br>
