bb property
The field name "b" fails to compile in proto1 because it conflicts with a local variable named "b" in one of the generated methods. Doh. This file needs to compile in proto1 to test backwards-compatibility.
Implementation
@$pb.TagNumber(1)
$core.int get bb => $_getIZ(0);
Implementation
@$pb.TagNumber(1)
set bb($core.int value) => $_setSignedInt32(0, value);
