.PP
The following operators are overloaded:
.PP
.Vb 1
\&    "" & | ^ ~ == !=
.Ve
.PP
Internally, bits are stored in ascending order using Perl vec function. Regardless
of machine order, big-endian or little-endian, vec function always considers first
string byte as the lowest byte and first bit within each byte as the lowest bit.
.PP
Things to keep in mind:
.PP
.Vb 5
\&    o Bit numbers range from 0 to (Size \- 1).
\&    o Bit data retieval methods provide options to data in ascending or
\&      descending bit order. Default is ascending bit order.
\&    o Stringyfy method provides an option to print data in ascending or
\&      descending bit order. Default is ascending bit order.
