You got me.
However, I also admit to having learned something today from the PEP.  That 2to3 actually replaces d.iteritems() with iter(d.items()).
In all my porting experience this conservative approach is redundant for my use cases which is usally just immediate iteration, so I have successfully replaced d.iteritems() with d.items() without issue.  For polyglot code, with rare exceptions simply using d.items() in both places is good enough, since IMHO the ill effects of creating temporary list objects is somewhat overstated.

The PEP however explicitly wants to do it "correctly" because testing is often limited.  So I withdraw my suggestion :)
