Presumably it is less common since octal and hexadecimal are more
compact and almost as easy to interpret as bit patterns?  Why would
you want them?

    Prelude> let bin = foldl...
    Prelude> 0o232
    Prelude> bin [0,1,0, 0,1,1, 0,1,0]
    Prelude> 0xD29A
    Prelude> bin [1,1,0,1, 0,0,1,0, 1,0,0,1, 1,0,1,0]

If I haven't seen further, it is by standing in the footprints of giants
