Detailed Description

Representation of a print() statement in the program.

It's currently necessary to have a special statement type for print() since strings aren't supported as first-class types in the language, but we need to be able to pass a formatting string as the first argument to print(). We also need this to be a variable argument function, which also isn't supported. Representing print() as a statement lets us work around both of those ugly little issues...
