Of course you can calculate it, but the
syntax looks quite different if you want to do
a.bit[22] = false:

a &= ~(1<<16);

Or if you want to test a bit:

if(a.bit[16])

instead of

if(a & (1<<16))

much more convenient for arrays:

ulong[100] a;

a.bit[3000] = true;

doing this directly with shifts is lousy (and error prone)

But ok. I see, it's not really awesome :-/
