You can look at this, it's more or less the same concept:

https://github.com/BBasile/iz/blob/master/import/iz/enumset.d#L226

Two things that important:
- enum members are not always integer numbers.
- enum used as flags is only fast when members values are 
consecutives.

I've recently discovered that it can even be used to make UDAs, 
what a "yeah" ;)
