How would you interate a collection of widgets without
polymorphism, i.e. any generic handling?
I mention the tool I use in the post.

We have interfaces and alias this with @disable so composition

So use a collection of interface instead of a collection of base
class. If you squint you could say that what I promote is a way
of doing inheritance, and I would agree. This is like doing
inheritance, with a bit worse syntax but with greater flexibility.
