If you want V8 like optimizations, you have to introduce a strict mode.
Python interpreter is known to leak its implementation (__class_ modification after creation, monkey patching with __getattr__, sys._getframe, eval/exec, deterministic call to __del__, no proper python API for libraries, etc.)
You have to plug all of those holes before having a chance to get a decent JIT.
Otherwise it will be just another JIT attempt, like Psyco, Unladen Swallow, Pyston.
