The itertools fixer (izip -> zip, among others), fails for the following code: from itertools import izip print msg % str(bool(symbol_swapped) and list(izip(*swap_dict).next()) or symbols) It gets converted to: print(msg % str(bool(symbol_swapped) and list(next(izip(*swap_dict))) or symbols)) (note how izip is still there) I've worked aroudn this by introducing tmp = izip(...) and using that, but it'd be nice if 2to3 caught it by default.

A smaller snippet to reproduce: izip().next() This gets converted to: next(izip()) It seems to me that the pattern of the itertools fixer doesn't match to izip().something(), and thus this is skipped.

I see two problems that cause the posted test cases to fail: 1. The 'next' fixer runs before the 'itertools' fixer and strips out a 'power' node. This keeps the 'itertools' fixer from matching. 2. The 'itertools' fixer does not handle any 'trailer' nodes after the itertool function application it is transforming. I have fixed both of these issues in the attached patch. Full test suite run; no regressions.

The patch is small and looks clean to me. Can someone take a look with a view to committing please, thanks.
