I'd like to see enum syntax for flug enum. So I dislike

You mean... binary basic syntax? That shouldn't be too hard.
So something like..?
Flags x;
with(Flags) {
x += one; //setflag
x -= two; //clearflag
x ^= four;//flipflag
x += [one,two]; //set flags multiple, same with flipping and
clearing
x -= [one,two];
x ^= [one,two];
I've added binary functionality. Looking at these notes I see I
forgot the enum/array part; And checking for binary true isn't
added yet. However I'll get to it sooner or later. Both opBinary
and opOpBinary are supported so far.
x += one; //setflag
x -= two; //clearflag
x ^= four;//flipflag
x &= two; //keeponly
x |= two; //setFlag, same as +=
//should work fine, as with all operations, const/immutable
safe.
Flags y = x + one;
if (x){} //compile error, will fix later
if (x != Flags()){} //should work, compare against .init
(probably 0)
if (x.state){} //works but you shouldn't depend on this
