Denis Shelomovskij:
Enumerations are in very poor state in D now.
...
By the way, current enums can be modified to correspond "list"
enumeration and flags can be added as library component.
I think D enums need to become a bit more strict (so you can't
equal elements of different enums). Later I think the messy
situation with enum attributes needs to be cleared up and
improved, removing most of the name clases between the current
attributes and enum item names
(http://d.puremagic.com/issues/show_bug.cgi?id=4997 ). And later
*simple* flags are implementable in Phobos.
First step is to make them less sloppy and more strict, otherwise
successive work will be founded on quicksand (but as long as such
threads generate no concrete answers from D designers, we are
just wasting time here).
In GitHub there are many patches open, applying several of them
will reduce many current pain points of using D.
