For some reason I spent two hours annotating a tiny chunk of the libstdc++ std::vector implementation that somebody asked about on reddit

https://www.reddit.com/r/cpp_questions/comments/1rgstr1/comment/o7v0sli/

@wako "If you don't know what that does it's a skill issue and a comment isn't going to change that."

😂😂😂

Honestly, I feel that so much. Yeah, weird or non-obvious shit needs comments, but… the reader needs to have a nonzero minimum level of understanding below which it's not your job to teach them CS 101 or <language> 101.

(And for reading let alone touching libstdc++, that minimum bar is *notably* higher.)
