14:52:16 <LeeF> chimezie: looked at algorithm in step 4 of 12.2.1 and tried to enumerate algebra constructs that arise from it
14:52:50 <LeeF> ... use a fold function to go from every combination of a left and right argument to 20 algebra expressions
14:53:05 <LeeF> ... idea would be to first list every permutation and then see which tests cover each

14:54:43 <ericP> }
14:55:10 <LeeF> ... express each of chimezie's patterns as a query
