Subject: [PATCH v4 18/19] qapi/expr.py: move related checks inside check_xxx functions
Date: Thu, 25 Mar 2021 02:03:55 -0400
Message-ID: <20210325060356.4040114-19-jsnow@redhat.com> (raw)
In-Reply-To: <20210325060356.4040114-1-jsnow@redhat.com>

There's not a big obvious difference between the types of checks that
happen in the main function versus the kind that happen in the
functions. Now they're in one place for each of the main types.

As part of the move, spell out the required and optional keywords so
they're obvious at a glance. Use tuples instead of lists for immutable
data, too.
