Ruby master - Feature #16832: Use #name rather than #inspect to build "uninitialized constant" er...

Nobu recommended creating an issue request here, so I won't comment on that in
itself - but I would like to point out that ruby users may wonder why/if/how
to use #name rather than #inspect, if applicable, so that should be considered
as well. Some may already struggle with #to_s versus #to_str distinction; we
should be considering this as well.
