Possibly, but there aren't really methods there now (it's opaque
currently), and anyway for this series I wanted to try to keep each
patch reasonably close to the existing code, to make the transition more
clear.

FWIW once I had some scripts to try to convert struct value to be more
like a class.  This is difficult to do in its entirety though.  There
are many potential methods.
