--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
As someone who regularly has to debug complicated template code, I think all
the information printed by g++ here is useful. There may be more compact ways
of giving the same information (use a shorthand for
"std::__cxx11::basic_string<_CharT, _Traits, _Alloc>"?), but I do want all the
information.

We could special case standard library code to print less details because
supposedly the library is perfect, we are debugging user code and not the
library, so some of the information is unnecessary, but I am not convinced this
is doable.
