(if using CoCalc, note that its c++ runner is a bit buggy; you always have to restart and run all as you can't run a cell multiple times, you must replace theoretically i fixed those last two. issues were with needing qualified vector<foo> return types with auto, and sometimes you must remove comments before the declaration of a function in a cellstd::vector<foo> in the return types and with an odd number of ' characters in the cells breaking everything. also the namespace hack for printTest is godawful, something is seriously messed up with how cling does or does not overload vs override declarations)
