I really dislike this feature. It's better to just say "we will come to this concept later", rather than make a fake syntax that does this (taken from the JEP)

I really dislike this feature. It's better to just say "we will come to this concept later", rather than make a fake syntax that does this (taken from the JEP) behind the scenes: new Object() { // the implicit class's body }.main(); It adds more confusion, as you are left explaining that you could not really run an instance method without instantiating the class -- it was just something fake for beginners.
