Description

I suggest to introduce a new AST transformation @InheritConstructors which can be placed on a class and the class with this annotation will inherit all the constructors of its super class.

For example:

class A {
    A() {}
    A(int arg) {}
    A(String arg) {}
}

@InheritConstructors
class B extends A {}

Then class B will be equal to:

class B extends A {
    B() { super() }
    B(int arg) { super(arg) }
    B(String arg) { super(arg) }
}

I think it is useful, especially for defining exceptions.
