I had similar questions reading the doc as well.
Or the name of a template full specialization?
But what bothered me a little was the note about the fact that
pretty_name() was not consistent across platforms/compilers.
This means you can't depend on it for generating a type-name-based
factory registration via a template taking the type to be
instantiated, and deducing the registration name from the type, in a
way that will be cross-compiler or cross-platform, w/o some kind of
post-processing to remove possible struct/class prefix, or namespace
prefix if desired. It's only a problem when the names are coming at
runtime from external strings, but that's a common enough use-case of
factories, to want boost::typeindex to support it, no? Thus I'd
request a safe_name() / consistent_name() method, that does the
pretty_name() post-processing once and for all, to yield
ns_name::type_name for example, or perhaps even a std::pair with NS
name as .first, and type name as .second.
