why does being able to switch on any enum trump
the ability to define constants without #define?

if you try, sizeof(foo)==4, but you'll need to remove
'd' since you can't have a string.  you can't switch on
a vlong or float.  would be nice, though.

the plan 9 style is never to typedef or name enums.
(though i saw one creep into the source recently.)
so the sizeof problem would naturally never come up.
if it were an error to name or typedef an enum
containing non-int members, there would be no
problem.
