True, but that's a fault of the implementation, which assumes POSIX is the only thing in town & makes questionable optimization choices, rather that of the language itself (for reference, the person above is referring to what's described here: https://snf.github.io/2019/02/13/shared-ptr-optimization/) | ||

> the language itself The "language" is conventionally thought of as the sum of the effects given by the { compiler + runtime libraries }. The "language" often specifies features that are implemented exclusively in target libraries, for example. You're correct to say that they're not "language features" but the two domains share a single label like "C++20" / "C11" - so unless you're designing the toolchain it's not as significant a difference. We're down to ~three compilers: gcc, clang, MSVC and three corresponding C++ libraries. | ||
