You can look at it that way, but it also hinders modular programming.

If I declare a variable to be local, I wouldn't expect it to fail and
be overridden by some global namespace pollution.

It is overridable, but not easily.

Might be nice to have some way to declare a var local to a function that
can be protected from random namespace pollution.
