Thank you! I looked for something similar a while ago and came up empty. Whenever I asked math friends the answer was always "there's too much variation so a book couldn't tell you everything", which is probably true but even common things would help. Someday I'd love to see a similar thing that's simply an operator to function index where you can read in code/pseudocode what an operator does on a (bounded for ease of reading) datatype.
