No, LK has nor real support for multiple inheritance, however, you can
simply copy functions and properties from one class to another (note
that $super, instanceof, etc. will not work correctly). LK uses this
for Trait-like constructs. E.g. look at NetRequestReporterTrait in
Network.js and it where it is used.
Object.subclass('ClassA', {
m1: function() { return 1},
m2: function() { return 2},
});
Object.subclass('ClassB', {
m2: function() { return 22 },
m3: function() { return 3 }
});
ClassA.subclass('ClassC', ClassB.prototype);
x = new ClassC();
x.m1() // 1
x.m2() // 22
x.m3() // 3
x instanceof ClassA // true
x instanceof ClassB // false
