I have to agree, at some point I thought I was getting to know Python
pretty well, then I read about iterators, and realized I understood
zero of what I had read about iterators.  Since I have unfortunately
avoided them, until I have time to really learn how they work.  It
sounds very cool and all, async type operations like threading with
out threads, but the magical syntax completely alludes me.  And it is
definitely above and beyond an average users level.  But I think that
is because it has it's root in functional programming which as I had
stated before is a complex subject on it's own.
