Er....one problem with first reading: you forgot to mention in the
while loop description that 'else:' would be executed if the exception
is raised, so the 'break' is a pseudo-break'.

Basic response: I *love* the iter(), sq_iter and __iter__ parts.
I tremble at seeing the rest.
Why not add a method to dictionaries .iteritems() and do

for (k, v) in dict.iteritems():
	pass

(dict.iteritems() would return an an iterator to the items)
