--- Comment #1 from Mark Isaacson <[email protected]> --- It would seem that the other querying methods: equalRange, lowerBound, upperBound (and quite a few others, like front) are also missing const correctness. I attempted a fix for that as well but that seems to be a bit over my head. Perhaps I'll find time to try my hand at a more thorough solution later in the week. --
