# obviously never do this.  it turns anything created with str() into a callable 
# ... but it would make an AMAZING prank. think of all the accidental exec statements! 
# think of the horrendous security holes!  I think I've discovered a bit of Python 
# code even more dangerous than https://github.com/ajalt/fuckitpy
#
# alas it doesn't make strings created without the str() function executable too.
