That said, as long as pro-mypy people are willing to make everyone else pay
a mypy reading tax for code let's try and reduce the cognitive burden.
* Duplicate type annotations should be a syntax error
Twelve years ago a wise man said to me "I suggest that you also propose a
new name for the resulting language"
I talked with many of you at PyCon about the costs of PEP 484. There are
plenty of people who have done a fine job promoting the benefits.
* It is not optional. Please stop saying that.

+1. There are no compelling language changes on the horizon ("yield

I committed some new telnetlib tests yesterday to the trunk and I can
see they are failing on Neal's setup but not what the failures are.
Ideally I like to get the information out of the buildbots but they
all seem to be hanging on stdio tests and quiting out.
Ideas? TIA,

We can't backport the __prepare__ syntax without requiring metaclass
definition on the 'class' line. Because the __metaclass__ definition
can be at the end of the class in 2.6 we can't find it until after we
execute the class and that is too late to use a custom dictionary.

The python binary is out of step with the test_itertools.py version.
You can generate this same error on your own box by reverting the

I think we both want class decorators as a more fine grained substitute
for __metaclass__ (fine grained as in declared per-class-instance instead
of this-class-and-all-its-children). I can think of three ways class
