bpo-32836: Remove obsolete code from symtable pass (GH-5680)
...
When comprehensions switched to using a nested scope, the old
code for generating a temporary name to hold the accumulation
target became redundant, but was never actually removed.

bpo-10544: Deprecate "yield" in comprehensions and generator expressions. (GH-4579)
...
The current behaviour of yield expressions inside comprehensions and
generator expressions is essentially an accident of implementation - it
arises implicitly from the way the compiler handles yield expressions inside
nested functions and generators.
Since the current behaviour wasn't deliberately designed, and is inherently
confusing, we're deprecating it, with no current plans to reintroduce it.
Instead, our advice will be to use a named nested generator definition
for cases where this behaviour is desired.

Other globals are excluded (see globals.txt and check-c-globals.py).

Fix potential NULL pointer dereference in update_symbols()

symtable_analyze() calls analyze_block() with bound=NULL. Theoretically
that NULL can be passed down to update_symbols(). update_symbols() may
deference NULL and pass it to PySet_Contains()

Add ast.Constant
...
Issue #26146 : Add a new kind of AST node: ast.Constant. It can be used by
external AST optimizers, but the compiler does not emit directly such node.
An optimizer can replace the following AST nodes with ast.Constant:
* ast.NameConstant: None, False, True
* ast.Num: int, float, complex
* ast.Str: str
* ast.Bytes: bytes
* ast.Tuple if items are constants too: tuple
* frozenset
Update code to accept ast.Constant instead of ast.Num and/or ast.Str:
* compiler
* docstrings
* ast.literal_eval()
* Tools/parser/unparse.py
