static if(__traits(isStaticFunction, Member) || (!isFunction!Member && is(typeof(&Member))))

enum bool hasStaticMember;

static if(hasMember!(T, member))

static if(!(__traits(isStaticFunction, Member) || (!isFunction!Member && is(typeof(&Member)))))

enum bool hasStaticMember;

static if(!(hasMember!(T, member)))

enum bool hasStaticMember;

}
