Variable declarations can go either way; Python requires you to name
all globals that you mutate, and to be careful when working with
nested functions. With declared variables, you name all locals, and
can enforce scoping and destructors without language features like
'with'. Both options are viable.

I absolutely agree with your third point. Treat 'em all as objects!
But of *course*, Java is "more object oriented" than Python. Everyone
knows that.
