Will Greece survive an exit?

While the words "Greek exit" or even the newly coined term "GREXIT" rolls off the tongue easily, in practice Greece exiting the Euro or the European Union will be anything but easy. When the Maastricht Treaty was signed in 1992, the treaty did not even build in a provision for an exit from the single currency, perhaps in the hope that no one will ever want to exit the Euro. But now that they are faced with the situation of a nation which may want to exit the Euro, what will be the process through which Greece could exit and how painful could it get?
