Appearance
A special specialization std::vector<bool>
compresses each item to a single bit.
For this special specialization, the indexing operator doesn't return bool&
.
Instead, it returns a reference to an auxillary class that defines both vecyVar[iIndex].flip()
and a cast-operator for getting and setting its bool
value.
