Well, I
already generate such structure at compile time using type traits based
decomposition and tag dispatching. The "runtime" part is just
acually feeding all parts of the type name string description (volatile,
const, repetition of *, array extent etc) to the ostringstream.

I don't think using type_info is a better solution as its output depends
on compiler and are sometimes non-existant.
