A bit vector is a resizable mutable sequence of bits. Bit vector words are found in the bit-vectors vocabulary.

Bit vectors form a class:

bit-vector

bit-vector? ( object -- ? )

Creating bit vectors:

>bit-vector ( seq -- vector )

<bit-vector> ( capacity -- vector )

Literal syntax:

?V{

If you don't care about initial capacity, a more elegant way to create a new bit vector is to write:
