// The series of i?_test.v files, do test different edge cases for
// interface table generation. The differences may seem very minor
// (placement of the interface declaration, whether or not there are
// helper methods, etc), but PLEASE do NOT be tempted to merge them in
// a single _test.v file. Debugging interface code generation issues
// is *much easier* when the _test.v files are very short and focused.
