It would look something like this:

• (void)myMethod:(ref CPString)aString { aString("new value") }

[Object myMethod:@reference(myString)];

@dereference would allow you to talk to it:

[@dereference(stringReference) length]

Essentially, @reference(X) is a macro that becomes

function (value) { this.set = function(x) { X = x; } this.get() { return x; } }

@dereference(X) is a macro that becomes

X.get()

More or less.
