So, is that a "yes" answer?

Actually, the case in the article is quite common in my practice - I
have an interface or a class that I'd rather implement as FSM. That's
why I added a simplified events support based on tuples. Though, I
couldn't find any automatic way to translate interface method calls
into events except by hand or with a code generator.
