I'm going to have one in the examples for the unordered associative
containers. If there's interest in making this part of boost proper I
suppose that's a possibility. You can see the example on the page at:
The code on that page hasn't been tested yet, so there's a good change
that it contains embarrassing bugs.
An official version would need to be made generic and work with locales.
I didn't do this, as I wanted to keep it simple, but I could include a
full-featured version as well.
