//current limitations:
// 1. Attributes are not processed
// 2. output type inference not implemented except Add
// 3. Type Attribute: 'optional' and 'Variadic hetergeneous' are ignored
// 4. type of string, complex64 and complex128 for input/output are ignored 
// 5. unsigned int are treated as signed one
