I have to work with C++ professionally one and off based on client requirements is there an _efficient_ resource that would allow me to keep up with all that has happened beyond C++14?
At the rate the committee adds stuff it feels like it is a full time job just to keep up.
Also is there any initiative within C++ to do a subset dialect with bowling alley guard rails? Something analog to the old C++ JFS standard, or something analog to dlang '-betterC' dialect flag?
Not sure if it's really what you are looking for, but the C++ Core Guidelines (https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines) are what I check when I have to touch a C++ code-base.
It precise which parts of C++ are to be used and which are to be avoided according the creators.

Yuck. They may have just hired yakuzas lawyers (yakuzas use a lawyers a lot, and are experts in exploiting legal loopholes (and sometimes participating in the creation of them)).
That's a shame to put money into this disgusting mafia.
