Hi again,

I can see you've disabled type demangling in 1.55 release to remove
the dependency. I really liked that feature, it made my logs more
readable.

Would you consider re-enabling it if the demangling function is
implemented in a separate header in boost/detail? There would be no
dependency on Boost.Units and in fact Boost.Units and my own code in
Boost.Log could be ported to it as well.

PS: The recently reviewed Boost.TypeIndex library will have similar
code as well, and it can be converted to use that code too. I really
hope that library gets accepted soon, so my plans of extracting
type_info_wrapper to Boost.Utility are currently on hold.
