I've seen BitField, but this is for a slightly different purpose, namely a
replacement for C's bit fields. I don't even know why we need BitField,
because it's in the language itself, perhaps some strange compiler doesn't
handle it? EnumSet OTOH is (not surprisingly ;-) a data type for a set of
values from an enum. Of course this could be implemented via bit fields, but
this would lose typing information (like in CompilationInfo's flags) and mix
the concept with its implementation.
In any case, EnumSet is not a big deal and g++ compiles it away almost
completely, leaving only a plain integral value, which is nice.
Cheers,
S.
