[New-bugs-announce] [issue36187] Get rid of NamedStore

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

The proposed PR refactors the code for assignment expression and removes the NamedStore value of the expr_context_ty enum added in issue35224. This value is undistinguished from Store except two places in Python/ast.c and Python/symtable.c, but in that cases the difference can be handled at one level upper (when process the NamedExpr expression).

As a side effect this PR fixes the following minor bug:

>>> (True := 1)
  File "<stdin>", line 1
SyntaxError: cannot delete True
