Sure it will work: it re-binds name myInt to something
different just before, exactly as it always did.  WHATEVER
myInt was before the
    myInt = 5
has absolutely NO relevance.

Yes.

Of course not.  Just like:

class Whatever(anybase): pass
x = Whatever()
x = "nah, better be a string"

Now printing x will print
    nah, better be a string
of course.  Name x has been re-bound.

Must be a pretty bad cold, Russell, or very interesting
medicine indeed:-).
