Well, if you can live with using compiler specific functionality here, then
you could demangle that name. g++ uses just the same string that would be
used in name mangling. Look into the cxxabi.h header. It provides a
function abi::__cxa_demangle() that can convert the name returned by
typeid(T).name() into what you want.

xpost&f'up2 gnu.g++.help, because that group is clearly more appropriate for
answers to my posting.
