# A golfed python 'accent'. Fully backwards compatible with python.
# NOT SUITED FOR DAY-TO-DAY PROGRAMMING!
# If you DO use it for a production (non-challenge/codegolf) program, I'm not
# responsible for anything bad that happens to you, your computer,
# your spare time, your code maintainability, any kittens that god might kill,
# or the tears of blood you will weep.
