It would make writing a general algorithm easier and more convenient since we would have to use `set()` functions instead of `operator[]` only for the ""external"" map types, and all the ""internal"" maps, which are created by the algorithm could be used as reference maps. Maybe it could also improve the efficiency in some cases, but it is not clear and wasn't tested.",task,closed,critical,LEMON 1.1 release,core,hg main,fixed,,,
