Might be better to test this without `-gsimple-template-names`, because it's a
more generally valuable feature than that?
Oh, but that "look for the child count through a pointer" issue comes up and
it's hard to reach this situation without `-gsimple-template-names`? (Maybe
indirectly - if you print a struct with a pointer - perhaps that doesn't do the
child count searching through the pointer?)
