Subject: [PATCH v4 12/19] qapi/expr.py: add type hint annotations
Date: Thu, 25 Mar 2021 02:03:49 -0400	[thread overview]
Message-ID: <20210325060356.4040114-13-jsnow@redhat.com> (raw)
In-Reply-To: <20210325060356.4040114-1-jsnow@redhat.com>

Annotations do not change runtime behavior.
This commit *only* adds annotations.

Signed-off-by: John Snow <jsnow@redhat.com>
