And this (mangling anon namespace symbols instead of making them static)
is a feature that I would dearly like to get rid of, or at least use more
rarely.  The reasons given for needing to make anonymous namespace symbols
global apply to rather theoretical cases, mainly involving the "export"
feature which we have not even implemented.  It seems an overly cautious
approach that creates more problems than it solves.
