bpo-36541: Add lib2to3 grammar PEP-570 pos-only arg parsing (GH-23759)
...
Add positional only args support to lib2to3 pgen2.
This adds 3.8's PEP-570 support to lib2to3's pgen2. lib2to3, while
being deprecated is still used by things to parse all versions of Python
code today. We need it to support parsing modern 3.8 and 3.9 constructs.
Also add tests for complex *expr and **expr's.

lib2to3: Support named assignment expressions (GH-12702)
...
There are two copies of the grammar -- the one used by Python itself as
Grammar/Grammar, and the one used by lib2to3 which has necessarily diverged at
Lib/lib2to3/Grammar.txt because it needs to support older syntax an we want it
to be reasonable stable to avoid requiring fixer rewrites.
This brings suport for syntax like `if x:= foo():` to match what the live
Python grammar does.
This should've been added at the time of the walrus operator itself, but lib2to3 being
independent is often overlooked. So we do consider this a bugfix rather than enhancement.

Remove binding of captured exceptions when not used to reduce the chances of creating cycles (GH-17246)
...
Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles.
See for example GH-13135
