No "real" concurrency but a generator can be seen as independent thread 
of code where the generator code is allowed to run when `next()` is 
called and stops itself when it ``yield``\s an object.  Sort of 
cooperative multitasking.  The name "yield" is often used in concurrent 
code like Java's or Io's `yield()` methods.
