Uhh, that's like saying there are no REAL floats in C, because you can
#define float int
And pointer tricks, well, you can do anything with raw memory access.
These aren't proofs that something doesn't exist, they're proofs that
trying to enforce privacy is bound to fail - so you may as well strip
that code from your compiler/interpreter and go with the Python style.
Much easier.

I agree with your point, just not your argument. :)
