<bit-vector>

A vector that contains <bit>s.  The vector may be treated as a series of 32-bit words, and may have Boolean operations performed over all its contents at once.

When treated as a series of words, each word is structured as follows

Element  0  1  ...  30 31 32 33 ... 62 63 64 65 ...
         +---------------+---------------+----------
Word     | LSB   0   MSB | LSB   1   MSB | LSB   2
         +---------------+---------------+----------

Make keywords

size:An instance of <integer> specifying the size of the bit vector in bits.  The default is 0.
fill:An instance of <bit> specifying an initial value for each element of the bit vector.  The default is 0.
round-up-size?:An instance of <boolean>.  If true, the bit vector is sized in 32-bit increments, sufficient to contain size bits.  For example, a size of 40 would result in a vector of 64 bits.  If false, the vector is sized to size bits exactly.  The default is #f.
copy-from:An instance of <bit-vector> that is copied to the new instance.  If the copy-from instance is shorter than this instance, remaining bits are filled as specified by fill.
