No. Python has objects, and names that refer to those objects. Objects
have a type, which can't change once the object is created. But a name may
refer to different objects of different types at different times.

Python never "converts" anything, except numeric types in expressions
(2+3.0, sqrt(5L)) and sometimes string/unicode.

Don't need to control all of "Burmese  territory".
Just prevent them from making trouble is enough.
