- Enums without tagnames can trigger bugs in SWIG, e.g. for an enum
     typedef enum { ... } myenum
  and a function
     void myfunction(const myenum *e);
  SWIG generates the incorrect cast
     (enum myenum const*) e
  whereas if the enum is given a tagname
     typedef enum tagmyenum { ... } myenum
  SWIG generates the correct cast
     (enum tagmyenum const*) e
