Hi Mirek,

How do you feel about adding a Bits::Set function that allows the user to put in packed bools? I was thinking about a function such as the following:

void Bits::VectorSet(int i, const dword bits32)
{
	ASSERT(i >= 0 && alloc >= 0);
	int q = i >> 5;
		
	if(q >= alloc)
		Expand(q);
		
	i &= 31;
		
	// Just place the input DWORD in position q in the Bits data buffer.
	bp[q] = bits32;
}

Maybe with some checks, this is just an idea. I mean, this function works in my testcase because I only work with multiples of 32. Even though, this could be used as an assumption to make it fast. It accepts a bitset dword and directly sets it. This allows efficient use of the Bits structure while preparing the actual packed bools structure with SSE2 instructions like _mm_movemask_epi8.

Thanks!
