operator: active-buffer

    description:
        active-buffer[N, t] seq
        active-buffer[N, t, op] seq
        an early version of 'actively' reading a sentence, and use back-ground knowledge to work out what is said
        not super impressive, and in many cases 'explain' does a better job.

    examples:
        -- learn a simple face:
        |body part: face> => 2|eye> + |nose> + 2|ear> + 2|lip> + |hair>
    
        active-buffer[7,0] (2|eye> + |nose>)
            0.375|body part: face>
            
        active-buffer[7,0] (2|eye> + |nose> + 2|ear> + 2|lip> + |hair>)
            |body part: face>
