 * Description:
 * One PyFunction object is created by the parser for each function found
 * in the casm input file. In addition, when a nested function appears in 
 * a casm file, there is a PyFunction object created before the outer function
 * calls the inner function. If variables in the outer function are referenced
 * by the inner function, a closure is created which is also a PyFunction 
 * object. Read more about closures in the text.
