if yu want tag enums a(And then use this tag) then this way
wouldnt work in generally as you will drown in combinatorical swamp
(and also on this i was writing before writing subtypes should
be defined on rightside

say you have real byg set of enums and you got 10 suptypes (tags) (A B C 
D E F G H I J) of
enyms each one have about 100 enums of that tag you then need
to define also types that have combination of tags AB AJ AD F G FGJ BD 
BG ....

and youre drowned

i dont know hovewer what you need to do as you write this way one could
sit and think what youre talking about - and i got no time
(typical for programming groups though and what i write is also
probably of this kind - describing some things in programming may be 
quite hermetic to read)

as to enums i dislike them a lot.. realy sometimes is better tu use 
'asd' and sometimes even strings and comepare by strcomp
