[issue9553] test_argparse.py: 80 failures if COLUMNS env var set to a value other than 80

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

I don't think it is worthwhile to jump through hoops to avoid calling the special methods.  Your patch also creates an unnecessary dependency on the internal implementation of EnvironmentVarGuard (ie: the fact that currently __enter__ happens to return self...this is *not* part of EnvironmentVarGuard's interface contract).

----------
stage: unit test needed -> patch review
