Live with grace. Write superb software.

Found this gem while reading the documentation from good ol' vim:

   What Vim calls true is anything that is not zero.  Zero is false.
        Vim automatically converts a string to a number when it is looking for
        a number.  When using a string that doesn't start with a digit the
        resulting number is zero.  Thus look out for this:
                :if "true"
        The "true" will be interpreted as a zero, thus as false!

First language that I know of, where checking references to stuff actually return false.
