Experimental C++ standard libraries

From cppreference.com
< cpp

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.
