PLW2901 - Is addition assignment in with block problematic code?

[eggplants]

In for loop, it is problematic to run addition assignment to the iterator variable. But can the same be said of the with clause?

I would like to know of examples where such code causes bugs in actual behavior.

My code encountered in PLW2901:

import contextlib
import gc
from collections.abc import Generator

from rdflib importGraph
from rdflib.namespace import FOAF, RDF


@contextlib.contextmanager
def open_graph(configuration: str) -> Generator[Graph, None, None]:
    g = Graph(store="Oxigraph")
    g.open(configuration)
    try:
        yield g
        g.serialize(f"{configuration}.ttl")
    finally:
        g.close()
        g.destroy(configuration)
        del g
        gc.collect()

...

with open_graph("foobar") as g:
    for graph in graphs:
        # Merging graphs into one
        g += graph  # error: `with` statement variable `g` overwritten by assignment target

Such examples are not currently included in the test.
