1. Is this absolute name with symlinks resolved?
2. Why there is a special case for __main__?
(i.e. Special cases aren't special enough to break the rules.)
3. What link should I click in Python reference to read
    about standard globals like __file__ and this change?
    https://docs.python.org/3.4/library/index.html
    something like this in PHP
