C++ Experimental C++ Features
https://en.cppreference.com/w/cpp/experimental
The C++ standards committee publishes experimental C++ language and library extensions for future standardization.
Note: until 2012, these publications used the TR (technical report) format. Since 2012 ISO procedure changed to use the TS (technical specification) format.
