In this example, the while loops are certainly not needed.  In a real
example, driven by input, states could be visited many times.  For
that, while loops are needed within generators.  Of course, any
generator *method* can be written as a plain method by rearranging
lines and saving persistent data as instance attributes.  But the
generator form will be faster in repeated execution and may be easier
to write.
