I think the concept is fine, but if they take off they're going to
bifurcate Erlang APIs into traditional API modules that take explicit
process refs/state and this other breed that somehow gets by without
them. Yuck!

IMO, this meme (coupling state and behavior) is way too fundamental to
have two major variants in a language.
