There is a nice way to realize how deeply wrong everything is with C++.. Suppose, I have a silly idea - I could recompile my mplayer+ffmpeg and, perhaps, emacs with clang4 with all the cool optimizations for my cheap crappy i3-6xxx CPU of my crappy Lenovo laptop. Seems like nobrainer. Now movies are less laggy. Why then wouldn't I recompile my mysql server with -stdlib=libc++ and -std=c++1x, -rtlib=compile-rt, using lld and -lomp? Oh fuck...
