Yeah, but we need DW_TAG_namespace to do it, and a version of GCC
providing that probably won't be released until next calendar year.  I
certainly don't use demangled names to do nested type deduction if we
have DW_TAG_namespace, but I do think it will be important for the
next two or three years.

Sounds good to me.
