Yes, but if you just do "p tblinfo[i].dobj.dump", you're only going to get
a number, right? The value-added for an enum type is that the debugger
knows which symbol to substitute for a numeric value when printing. But
that stops working if what's in the variable is some OR of the values the
debugger knows about.
