This would be similar to dictionaries where there is more than one thing that you may want to iterate over: * iter(d) iterates over keys * d.iterkeys() iterates over keys * d.itervalues() iterates over values * d.iteritems() iterates over (key, value) pairs So having an iterchildren() method for row objects would fit this pattern pretty well.

I kinda would have expected that to iterate over values. This may be more convenient, though.
