Great, I look forward to reading it.

Yes, well, there is always that.  Certainly it seems like a solution
for C++ will initially have to get recreate namespace info from
DW_AT_MIPS_linkage_name, and there's no way that we'll be able to
allow users to use symbol names as if all the appropriate using
directives were in effect, since that information simply isn't in the
debug information that GCC is currently producing.  (Though that's not
the end of the world: we should be able to do name lookup using C++'s
name resolution rules based on the enclosing function and its
arguments, presumably.)
