After crafting my own `type_info_ptr` as a thin wrapper to be able to 
use `std::type_info` as key in maps, I found out about the new 
`std::type_index` in C++11.

It seems that a C++03 implementation would be trivial, except for the 
hashing functionality. Could that functionality be built by leveraging 
implementation specific details like whether there is only one 
`type_info` instance for each type, or whether the name member function 
returns distinct values?

I believe it would be a nice addition to Boost, perhaps as part of the 
utility library. It would be useful for those wanting to use C++11 
features while still writing C++03 compatible code.
