Classes Extensions

warning

At this moment, Drift does not implement classes extensions.

class A {
    static {
        let abc
    }
}

extend class A {
    static {
        let def         // The new attribute def is added to A class
    }
}

print(A.def)            // Correct with extension

Extensions files should be named following the pattern ClassName.ExtensionName.drift.

Sometimes, it is interesting to extend an existing Class' members, for example, to split Class definition in many files, or enrich an external Class. It is straightforward in Drift.
