Better use itertools.cycle if for any iterable.</p>

Revision 7. </p> <p>Solution to the Hamming Number problem. Demonstrates a lazy evaluation evaluation technique using itertools.tee() to feed an iterator into itself. This is a common technique with Haskell. The deferred_output() function is the key technique for implementing a forward reference to the output of the stream.</p>
