4) The lookup table does not seem to discriminate among different
precisions. Presuming the last argument to adaptivesimpson() would
be used or the precision be coupled to Digits. Then the lookup map
would have to hold the precision as well (on the key side, not the
value side). Otherwise it becomes impossible to re-run an
integration with a higher precision goal.
Best wishes
