I can't stop people from forking the language to do experiments, but
one of the goals I have for the moratorium is actually to *reduce* the
interest in core language changes, and to *raise* the barrier to
entry. Most language change proposals are just fluff, and they will be
just as unneeded three years from now as they are today. Once the
moratorium is lifted, users should be able expect the normal, slow,
conservative evolution of the language to continue -- not to see the
floodgates lifted for a barrage of new features.
