LGTM in principle.

Now the question is -- how do we test it? There are multiple libstdc++ library versions in the wild and we must not break any of them. We do have some testing on CUDA test bots (which I've just discovered to be silently broken for a while now), but they do not cover recent libstdc++ versions.
