[Pitch] Global actors

1. I can create an actor by first creating a global actor, and then doing " @myActor class XYZ " instead of " actor XYZ ". So you could perhaps argue that " actor XYZ " is syntactic sugar for " @tempPrivateActor class XYZ "...

This is incorrect. Consider the example of actor BankAccount. Each instance of a BankAccount protects its state from every other instance of a BankAccount. A similar class would not with a global actor applied.
