* Remove the private assignment-expression marker
Why:
extend_namedexpr_scope() already propagates assignment-expression
targets and records DEF_GLOBAL or DEF_NONLOCAL in comprehension scopes.
ASSIGNED_IN_COMPREHENSION remained only for conflict checks. Its private
bit overlaps CPython's packed LOCAL scope bit.
Changes:
- Register assignment-expression targets as ordinary assignments.
- Detect later target conflicts from existing declaration flags.

* Remove the private comprehension iterator flag
Why:
ITER duplicates the DEF_LOCAL and DEF_COMP_ITER facts already recorded
for comprehension targets. Its private bit also overlaps CPython's
packed scope field.
Changes:
- Use those flags for rebinding checks and local restoration around
inlined comprehensions.

* Preserve source names in named-expression diagnostics
Why:
Assignment-expression diagnostics exposed the mangled keys used for
symbol-table lookup. CPython reports identifiers as written in source.
Changes:
- Use source names in both comprehension conflict diagnostics.
- Enable test_named_expression_invalid_mangled_class_variables.

This directory contains all of the Python files that make up the standard
library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7
branch), with slight modifications to allow them to work under RustPython. The
current goal is to complete the standard library with as few modifications as
possible. Current modifications are just temporary workarounds for bugs/missing
feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
