This is basically what IronPython does already.  A sufficiently clever
implementation can make the current semantics go fast enough.  Thus,
we'd only need changes to the compiler, not even changes to the
language.  This is the most attractive option to me (see PEP 267).

I don't like the PEP 329 approach because it adds extra complexity to
each module to work around a limitation of the current implementation
that will almost surely disappear one day.
