This declares the method to take the union of Set and FrozenSet
rather than AbstractSet since that is where `difference()`
(used by `assertSetEqual()`) is defined.
* move cgi to 2and3 and add types
This is pretty stable between Python 2 and 3, and not very well documented.
* fix CI failures
* adjust comment
(want to force Travis to re-run)
* give up on overriding values
Also fix signature of IO.seek, IO.truncate, IO.write, and MutableMapping.update
Fixes#1016
Note: I couldn't put typing.pyi in 2and3 because of an import cycle when adding `import sys` to 2/typing.pyi
* add compileall stubs to 3 and add types to the ones in 2
Didn't merge the stubs because all functions have additional parameters since 3.2,
so there would be no shared code between 2 and 3.
* add comment
- Add sys.version_info checks (mypy now supports them)
- Went over Python 3 docs and corrected a few things
- Reexport things that are imported from opcode
CONTRIBUTING.md says to prefer ... Not the most impactful change but fixing
these will allow us to lint for it in the future and get a consistent style.
The stubs for `unittest.TestCase.assertCountEqual()` specify the parameters are Sequences; in fact the method works fine with Iterables, as the first thing the method does is convert them to lists. [1] The docs do say sequences, but it appears there is no reason they cannot be Iterables.

* Complete the tokenize module type hints
* Add missing import for Optional
* Use a 3.5-style named tuple, untokenize speaks with forked tongue so use Any
* Use explicit types for fields
"> (3,)" works but looks like the code is checking for Python 4.
"<= (3, 5)" was intended to check for versions up to and including 3.5, and probably works that
way in current type checkers. However, sys.version_info is actually a 5-tuple that is greater
than (3, 5), so a hypothetical type checker that uses the full version info would interpret
this check incorrectly.
This ensures that all version_info comparisons use <, >=, ==, or !=.
Both mypy and pytype only use the major and minor version in type checking. Using
checks like "sys.version_info >= (3, 4, 4)" won't actually work properly for
people type checking their code using version 3.4, because (3, 4) >= (3, 4, 4) will
always be false (at least in mypy's approach; not sure if pytype is different).
