I disagree.  Or at least I'll say "it depends."  All you really need in this
case is a function that you call with the old critter state and you get back
a new critter state.  That function could simply take a record, which
includes either a state variable or fun, and returns a new record.  Or it
could send an update message to a process and wait for the result.  It
doesn't matter.  There's no true concurrency here.
