if you find declarative static typing programmer-friendly, then Python 
is definitively not for you, and you'd better look for something else 
(Java ?). FWIW, the first and main reason for stating typing is about 
compiler's hint and raw performances, not "type-safety".

absolutely no need for this kind of "help")
