Description Simon Werbeck 2013-04-05 12:37:29 UTC 
It is possible to chain up to a class that is not listed as base class:

public class Foo {
	public Foo.foo () {}
}

public class Bar {
	public Bar () {
		Foo.foo (); // chain up
	}
}

void main() {
}

The generated construction code:

Bar* bar_construct (GType object_type) {
	Bar* self = NULL;
	self = (Bar*) foo_construct_foo (object_type);
	return self;
}
Comment 1 Michael 'Mickey' Lauer 2018-02-23 20:16:50 UTC 
With Vala master your sample is rejected with:

yo.vala:7.3-7.12: error: use `new' operator to create new objects
		Foo.foo (); // chain up
		^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)

Is that sufficient or could come up with another test case for this problem?
