People may use auto-fill in IDE a lot (I do), so maybe starting methods
from name_* is more auto-fill friendly:
* const char* name() // same as std::type_info::name()
* const char* name_raw() //
* std::string name_pretty() // was name_demangled()
In this way you just type name_ and see all the available name methods.
