1. Because Pony is both type and exception safe, actors (the Pony equivalent of an Erlang process) don't fail in the catastrophic sense. Right now, if an actor wants to report that it can't go on to some other actor, it just sends out messages. Obviously, we are big fans of Erlang, and big fans of the Erlang supervisor pattern, so we'll be writing a Pony package that puts a nice interface around this.

2. Yes! Pony has first class pattern matching already (along with algebraic data types, i.e. tuple types, union types, and intersection types, to make pattern matching really useful). It allows matching both on type and on standard or programmer defined structural equality. As I mentioned, we're big Erlang fans, so we definitely won't ignore stuff like this.
