Wow!!! This means that one can call #createTwin, modify the AST, and simply call it! Impressive!!!

You need to handle invalidation yourself, too. (for now). I want to first concentrate on purely “annotation” based MOP: instead of changing the AST it is annotated with MetaLinks. When a link is set, the twin creation + invalidation happens. When the last Link is removed, the twin disappears automatically.

Is it per default in Pharo 40516?

Yes. Marcus
