Iterating of some structure and removing elements thereby is always errorprone and should be avoided. But: In case of AA, I've got the feeling, that it might be safe:foreach (k,v;ways) if (v.empty) ways.remove(k);Do you agree? Or is there a better way to achieve this?
It compiles and it runs without throwing any RangeError... So it appears to be safe. Otherwise it'd be a bug that there's not error.
