    Yes, exactly. Which means that, while the speed gains are real, they only apply in cases where your libc is dangerously defective.

    > given not-pathologically-short line length limits like 20 characters Poor phrasing; 20 characters was meant as a example of a limit that is pathologically short.

    Of course, you also need to use solid gold audio cables, or you're just throwing away the extra precision via poor signal fidelity.

    I hope to write code that warrants a description at least twice as scathing as this one. But, you know, on purpose; when I'm intentionally fucking with someone. (I don't know of Ma…

    You're thinking of "self-aggrandizing" (and I think doctorpangloss is too, although I'm less certain since they didn't mention Wolfram).

    You do need (some subset of) associativity: (y0 * x) * x ?= y0 * (x * x) y1 * x ?= y0 * x y2 ?= y1 y2 is not in general constrained to be the same as y1 otherwise.
