I am -0 on changing it to call iter().  I do like the distinction from a 'for'
loop and leaving an emphasis for template blocks (or blocks, or whatever hip
term you crazy kids are using for these things at the moment) to use
generators.  As I said before, I am viewing these blocks as a construct for
external control of generators, not as a snazzy 'for' loop.
