I'm guessing that you ran into an issue where you tried to called operator[] on a const map and the compiler complained. This is what happens with regular stl maps. The solution there is to use the at function, which works the same as operator[] except it throws an error is the key doesn't exist rather than creating a new element.

I could also be okay with creating a const version of operator[] that calls at on the underlying map.
