This also works:alias F = MySuperLongNameFlag; auto flag = F.A | F.B | F.C | F.D; set_flags(F.A | F.B | F.C | F.D);It's similar to setting a local variable to some complex expression, just so you don't have to repeat that expression multiple times.
It's a misconception of the problem that the DIP tried to solve. What the DIP tried to solve is that the compiler should know that you are using an enum member. Actually I even think this should work without any special syntax, as a "last resort", let's say. But as you've explained, through Mike's report, this causes problems for D because the identifier resolution is tied to a particular implementation, i.e your fast symtabs.
