[$] New features in C++26

ISO releases new C++
language standards on a three-year cadence; now that it's been
more than a year since the finalization of
C++23, we have a good idea of what

features could be adopted for
C++26 — although proposals can
still be submitted until January 2025. Of particular interest is the addition of
support for

hazard pointers and

user-space read-copy-update (RCU).
Even though C++26 is not yet a standard, many of the proposed features are already
available to experiment with in GCC or Clang.
