I can't remember what my degeneracy pun was. There's no degeneracy.
bit-d-generate is a common lisp native pbm image format package with
bit array -> pbm ; and
pbm -> generator function (of 1s and 0s).
pbm is a historical 80s binary image format with two lines of ascii
headers, followed by some bits.

with junk at the end to fill out the last 8 bit byte.
My point is a recognisable dense uncompressed image format for storing
my binary hopfield nets. I guess it's superseded in modern times by a
binary palette png image with UNCOMPRESSABLE flagged DEFLATE
compression. However the format is very simple, though having digits
encoded as ascii text in the header lines is weird. I didn't attempt to
handle the ignoring of whitespace or comment lines. My reader generator
function only closes the file when attempting to generate the next bit,
and there is no next bit, which propagates a simple-error to you (after
closing the file).
I found the netpbm utility was a little unreliable, but imagemagick
grokked my meaning.
