An interpeter for pyg, the golfed python. Fully backwards compatible with python.

#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.
