makeByU
We can replace makeBy with makeByU if we uncurry its second argument. This will improve performance (a negligible amount in our example):
...makeByU(52, (. i) => switch (i / 13, i mod 13) { | (0, rank) => {suit: Hearts, rank: rank + 1} | (1, rank) => {suit: Diamonds, rank: rank + 1} | (2, rank) => {suit: Spades, rank: rank + 1} | (3, rank) => {suit: Clubs, rank: rank + 1} | _ => assert(false) })...
The dot syntax requires parentheses around i.
