IIRC Stroustrup mentions a desire for features such as these for versions of C++ after C++17.

C++11 c++14 c++17 does that mean that we might see a match statement in c++20? It would be a significant addition - similar in complexity to anonymous functions.

i remember that Bjarne Stroustrup held a talk in cppcon15 where he talked a lot about the GSL library [1] - it would add type annotations that can be checked by a tool, so as to check for potential memory problems (to me that sounds like a poor man's borrow checker).

One year later: i see the template library [1] but i don't see the analysis tool. Does anybody know what happened with this initiative?

The tools are called clang tidy and Visual Studio 2015 Update 3.

Other vendors might eventually add support as well.
