driveby:

I'm generally in favor of this, just wonder if it falls a bit on the
caveat-for-const in the C++ style guide. "However, do not go crazy with const.
Something like const int * const * const x; is likely overkill, even if it
accurately describes how const x is. Focus on what's really useful to know: in
this case, const int** x is probably sufficient."

LGTM

These are consistent with the rest of the file.
