It is experimental, and it may be removed in +// future releases. + +// A bitset of size N, using words of type _WordT, will have +// N % (sizeof(_WordT) * CHAR_BIT) unused bits. (They are the high- +// order bits in the highest word.) It is a class invariant +// of class bitset<> that those unused bits are always zero. + +// Most of the actual code isn't contained in bitset<> itself, but in the +// base class _Base_bitset. The base class works with whole words, not with +// individual bits.
