Indeed, although it is not 100% true, because we also have an
interpreter.  But it's still 95% true.  All in all micro-optimizations
that gain at most some small number of percents in CPython's run-time
and that don't give anything anyway with the JIT are particularly
pointless in PyPy.  Well, let's just say I'm amazed at the energy
people can put in endless threads of discussion.  Feel free to do it,
because it's usually easy to adapt our interpreter, and our JIT
follows automatically.

I would very naively suggest the following: How about putting the same
amount of effort into bringing forward http://hotpy.blogspot.com/

A bientôt,
