+# Potential C member name collision

+# putting union branch members in a separate namespace from QMP members.
+# This is true even for non-unions, because it is possible to convert a
+# struct to flat union while remaining backwards compatible in QMP.
+# TODO - we could munge the member name to 'q_u' to avoid the collision
