That was precisely what I was going to say. I don't recognize any of that.

Yeah, I recognize the lambda expressions and not much else. How does the new stuff even interact with the older features? I can't even tell if something is recommended or deprecated anymore. Can you imagine the sheer work of maintaining a compiler for this thing? Really makes me appreciate the relative simplicity of C.

On a positive note, it looks like the standard library became amazing. It seems really well designed. Contains things that used to be preprocessor definitions, lots of very popular functionality, good symbol names and no cryptic abbreviations anywhere. Did it absorb some of boost?

I, uh, recognized "#include", but not much else...
