This implementation SHOULD work for that I'd expect, but we're currently re-visiting it in order to get the names to be demanglable (at least on Linux, and will likely delay an RFC).  We've used the Itanium Mangler plus some modification to the lambda mangling to make it depend on source-lines instead of arbitrary ordering.
