The change broke the backwards compatibility of parsing behavior in a
patch release of Python (3.7.6). A decision was taken to revert this
patch in 3.7.7.
In https://bugs.python.org/issue27657 it was decided that the previous

bpo-39606: allow closing async generators that are already closed (GH-18475) (GH-18502)
The fix for [bpo-39386](https://bugs.python.org/issue39386) attempted to make it so you couldn't reuse a
agen.aclose() coroutine object. It accidentally also prevented you
from calling aclose() at all on an async generator that was already
closed or exhausted. This commit fixes it so we're only blocking the
actually illegal cases, while allowing the legal cases.
The new tests failed before this patch. Also confirmed that this fixes
the test failures we were seeing in Trio with Python dev builds:

bpo-21016: pydoc and trace use sysconfig (GH-18476)
bpo-21016, bpo-1294959: The pydoc and trace modules now use the
sysconfig module to get the path to the Python standard library, to
support uncommon installation path like /usr/lib64/python3.9/ on
Fedora.
bpo-38374: Remove weakref.ReferenceError from docs (GH-18452)
Reflecting changes to the code, removed weakref.ReferenceError from weakref.rst and exceptions.rst.
Issue submitter provided evidence that the `weakref.ReferenceError` alias for `ReferenceError` was removed from the code in 2007. Working with @gvanrossum at PyCascades CPython sprint we looked at the code and confirmed that `weakref.ReferenceError` was no longer in `weakref.py`.
Based on that analysis I removed references `weakref.ReferenceError` from the two documents where it was still being referenced: `weakref.rst` and `exceptions.rst`.

bpo-39274: Ensure Fraction.__bool__() returns a bool (GH-18017)
Some numerator types used (specifically NumPy) decides to not
return a Python boolean for the "a != b" operation. Using the equivalent
call to bool() guarantees a bool return also for such types.

bpo-39485: fix corner-case in method-detection of mock (GH-18256)
Replace check for whether something is a method in the mock module. The
previous version fails on PyPy, because there no method wrappers exist
(everything looks like a regular Python-defined function). Thus the
isinstance(getattr(result, '__get__', None), MethodWrapperTypes) check
returns True for any descriptor, not just methods.
This condition could also return erroneously True in CPython for
C-defined descriptors.
Instead to decide whether something is a method, just check directly
whether it's a function defined on the class. This passes all tests on
CPython and fixes the bug on PyPy.

bpo-38400 Don't check for NULL linked list pointers in _PyObject_IsFreed (GH-16630)
Some objects like Py_None are not initialized with conventional means
that prepare the circular linked list pointers, leaving them unlinked
from the rest of the objects. For those objects, NULL pointers does
not mean that they are freed, so we need to skip the check in those
cases.

The previous double colon was wrongly place directly after Therefore.
Which produced a block without syntax highlighting. This fixes it

properly highlights the python code.

[3.7] bpo-16575: Disabled checks for union types being passed by value. (GH-17960) (GH-17970)
Although the underlying libffi issue remains open, adding these
checks have caused problems in third-party projects which are in
widespread use. See the issue for examples.
This affects both shallow and deep copying.
My idea for a fix is to add property objects to the list of "atomic" objects in the copy module.
These already include types like functions and type objects.
I also added property objects to the unit tests test_copy_atomic and test_deepcopy_atomic. This is my first PR, and it's highly likely I've made some mistake, so please be kind :)
