 * Description:
 * PyBuiltinConcat is a built-in function (i.e. PyCallable) for the 
 * CoCo concat functionality. This built-in function takes an argument and 
 * calls the "concat" attribute that is associated with the type of the 
 * argument. Currently, only PyFunList objects support concatenation. List
 * elements must be concatable. Likely the elements of the PyFunList are 
 * strings which can be concatenated.
