You can work with an array of bits (a bitstring ) with
the vec operator, setting bit number
123, clearing bit number 456, and checking to see the state of bit 789.
Bitstrings may be of arbitrary size. The vec operator can also
work with chunks of other sizes, as long as the size is a small power of
two, so it’s useful if you need to view a string as a compact array of
nybbles, say. See the perlfunc manpage.
