[New-bugs-announce] [issue22294] 2to3 consuming_calls: len, min, max, zip, map, reduce, filter, dict, xrange

[Edward O]

New submission from Edward O:

This is a patch for issues similar to #16573
With this patch, the following new tests are now unchanged:

r = dict(zip(s, range(len(s))), **d)
r = len(filter(attrgetter('t'), self.a))
r = min(map(methodcaller('f'), self.a))
max(map(node.id, self.nodes)) + 1 if self.nodes else 0
reduce(set.union, map(f, self.a))

Note that as part of the patch, the range transformation now calls the generic in_special_context in addition to the customized one (which. I guess, should be removed, but I didn't dare).

All existing tests pass, but the patterns used may not be strict enough, though I tried to stick to how it was done for other consuming calls.
