You could also use some of the map.e routines, though this is not p2js compatible, because of a clash over get() in map.e and as a builtin, but of course you could easily take a copy of map.e and rename get() [assuming that is acceptable], not that you should ever actually need to, since map.e is itself only a compatibility shim anyway.
