Yes, yes, yes!  I posted about this a while back, hoping to start just such
a
discussion, but of course I don't know anything about gdb internals.  I'm
new
to C++ and the STL. It was mind-boggling that The Experts encourage vectors
instead of C++ arrays, and standard lists instead of home-grown ones, yet if
I put my data into STL containers,  I can't actually look at it during
debugging without writing my own data-display wrappers for all my classes,
or
possibly learning the internals of libc++-v3.

As a C++ user, I would be thrilled to have *any* debug format that allowed
me
to display my own data.  None of the formats works now anyway, so if all I
had to do was change a makefile and upgrade my gdb, I'd be dancing on my
desk.  (That may be a good reason not to implement it.)
