No, it does not have to be async. My impressions from using Squeak regarding this matter: 1. You can send any message to any object. In case the object does not have a suitable handler, you will get an exception: <object> does not understand <message>. The whole thing is very dynamic. 2. There is no `static` BS like in c# or java.
