Hi Buddy,

Thanks for the idea!

This "two-part macro" trick will work:
#define $MkEnum(name$) \
struct name$ {\
   typedef enum {

#define $EndEnum(name$) \
   } Type;\
   Type m;\
   name$(Type in) : m(in) { }\
   operator Type () const { return m; }\
}

In use:

$MkEnum(Marx)
	Groucho, Chico, Harpo, Gummo, Zeppo, Karl = 86
$EndEnum(Marx);

Voila!  Slightly awkward, but acceptable.  It could all be put on one line, 
but I'm not sure if that'd be better or worse.

Note:  C++ only, no C.

Thanks,
--Eljay
