@kossebau: did you try the C++ Standard (working draft): https://isocpp.org/blog/2013/10/n3797-working-draft-standard-for-programming-language-c-stefanus-du-toit This ^ one is circa 2012. All the sources used to generate the C++ Standard drafts are maintained in this git repo: https://github.com/cplusplus/draft (Reading the standard feels like reading legalese, but it's quite informative albeit very^Wslightly mind boggling). Sorry if this is off-topic. INLINE COMMENTS > kossebau wrote in plugin.cpp:196 > Confirmed by experiments.
