It does, however, when I try this I get errors about no viable overloaded '='.
I've tried both declaring my ConfigEntMap::iterators before hand and assigning
them in the declaration, the errors differ slightly, but it all boils down to
the compiler not being able to decide if it should be an implicit copy or an
implicit move. I assume it should be a copy, but I'm not sure how to go about
specifying that in the code.
