You can explain it yourself or just drop me a link (or both).
Right now I'm learning Python 2.x but I plan on learning Python 3.x as well.

Stephen,
I've come into this thread late, but it looks like you're lamenting the fact
you can stipulate complex iterations on a single line, which can be nice. I'd

More accurately it translates the restricted subset to C and then *that* can
be compiled. Some code can get quite dramatic speed improvements - t
