modern programming is like,

"if you're using bongo.rs to parse http headers, you will need to also install bepis to get buffered read support. but please note that bepis switched to using sasquatch for parallel tokenization as of version 0.0.67, so you will need the bongo-sasquatch extension crate as well."

old-time programming is like,

"i made a typo in this function in 1993. theo de raadt got so angry he punched a wall when he saw it. for ABI compatibility reasons, we shan't fix the typo."
