(I notice that I keep following up on my own posts...)

Perhaps this is really a version of ets:new()...?


ets:new(found_set, [{type, ordered_set},
                    {select, {Tab, Pattern}}]).

This would create a new ETS table, and populate it with the
results from ets:select(Tab, Pattern).

The next step would be to perform a join operation. ;-)
