17  Declare the methods needed by an object that can be printed,
18  both from C++ and Python. Each value-type class should have an
19  IMP_SHOWABLE() call internal to it and an IMP_OUTPUT_OPERATOR()
20  call external to it.
21 
22  The suffixs are the number of template arguments that the
23  object has (eg _1 means one template argument). _D means
24  one integer template argument.
