As already discussed, it's synchronized_value in the Concurrency TS V2.
It's sorted by gcc already.

This entire thread is giving me deja vu. The idea of locking on every
access has already been discussed and rejected as the wrong granularity
(and the committee will not approve such misguided proposals). The idea of
a locked value with an accessor taking a callable to operate on the value
is already in a C++ TS.
