Yes, it's a formal review.

In short:
* extended_typeinfo is not compatible with std::type_info and is hard to use
* TypeIndex is a correctly working std::type_info that does not require
RTTI + has other bonuses
* detail/sp_typeinfo.hpp implements part of TypeIndex functionality,
without workarounds for compiler issues

Longer description:

Serialization library is created to make a storeable in archive and
portable between compilers type identifications. It's interface is not
close to the interface of Standard Library, it requires A LOT of code to
make typeids work (see example at

TypeIndex is designed to be simple, fast and lightweight. It's a drop-in
replacement for std::type_info with big set of workarounds for issues of
different compilers and an extension to get human readable type names + it
contains a C++11 type_index class and works without RTTI. It does not
require user's support code to work. Take a look at this page:
see how Standard Library classes and methods are mapped to the

TypeIndex is close to detail/sp_typeinfo.hpp (it's just a very very
enchanted sp_typeinfo that does not adds macro, embeds workarounds and has
interface of std::type_info + other features from paragraph above)
