Subject: [PATCH v4 09/19] qapi/expr.py: Check type of 'data' member
Date: Thu, 25 Mar 2021 02:03:46 -0400	[thread overview]
Message-ID: <20210325060356.4040114-10-jsnow@redhat.com> (raw)
In-Reply-To: <20210325060356.4040114-1-jsnow@redhat.com>

We don't actually check, so the user can get some unpleasant stacktraces.
Formalize it.
