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.
Using izip with up to 6 arguments will retain the arguments' type information,
using izip with 7 and more arguments will discard type information about the
generated tuple items.
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
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.
Fixes#975
And a few more things I noticed while reading the tempfile docs.
In 3.5, most functions in tempfile were changed to accept either str or bytes in their prefix and suffix arguments, and return bytes or str accordingly. This seemed like a case for AnyStr.
We were missing tempdirb and tempprefixb, added in 3.5.
TemporaryFile and others were declared as returning BinaryIO, but they actually return either binary or text IO depending on the mode passed in. I changed the return type to IO[Any], similar to builtins.open.
* Make pickle accept IO[str] instead of BinaryIO.
This makes the following code work:
pickle.Unpickler(cStringIO.StringIO())
(Which didn't work before because cStringIO.StringIO inherits "only"
from IO[str], not BinaryIO)
* Use bytes instead of str.
* Fix a few return types in stdlib/2/inspect.pyi.
* Rename _FrameRecord to _FrameInfo
* Correct some return types in itertools.pyi from Iterable to Iterator.
* Missing special attributes of class instances inherited from object
* object.__reduce__ returns a tuple
It's up to its inheritors to return either a tuple or a string.
