So, who thinks this idea is not actually inherently inconsistent please
please specify in the documentation, based on your rationale, how are
objects supposed to behave in the disposed state.  Namely with respect
to (not) keeping impossible invariants, returning nontrivial
no-longer-available values, methods that normally create or acquire
something before returning it and other practical issues.  Or say that
there can be certain things the object owners may not do with disposed
objects.  Or anything.  This

     The object is also expected to be able to answer client method
     invocations (with possibly an error code but no memory violation)
     until finalize is executed.

has as, a practical guide, approximately the same value as ‘people
should live together in peace’.

Thank you in advance,
