…Or that, I suppose.  Seems like busy-work to me, though.  We never had such restrictions before, on putfields.  Since a single init-method can issue duplicate putfields (in the VM), there does not seem to be any harm in having a this-calling init method issuing additional duplicate pufields.

Really, I’m OK with a rule here, but would prefer not to issue a rule.
