Classes will not work for the same reason that you can never use a class 
object as an enum with manifest constants. It's a long-standing bug that 
structs don't work as enums (other than manifest constants) even though 
they're supposed to according to TDPL:

be made to work. Regardless, it should be reported that tuples don't work as 
enums other than manifest constants.
