| 2024-12-30 17:03:28 +0100 | <prsteele> | Yup, that makes sense, thanks! And also thanks for your notes on ST annotations |
| 2024-12-30 17:03:03 +0100 | <Leary> | prsteele: The triviality of the reverse is why you should do it the other way around in the first place. Use the same convention as in base: call your class methods `oldNameBy` and have them take explicit `a -> a -> Ordering` arguments. At the top level, define `oldName = oldNameBy compare`. |

| 2024-12-30 16:59:46 +0100 | <prsteele> | `newtype Comparing a = Comparing (a -> a -> Ordering, a)` instance. This seems _okay_, except that it would merely be convention that all values of that type have equivalent functions embedded. (You'd get no protection from passing `compare` versus `flip compare`, for example.) |
| 2024-12-30 16:59:46 +0100 | <prsteele> | I've implemented a class that has an `Ord a` constraint. This is all well and good, but now I find myself wanting to use this class when I only have a `a -> a -> Ordering` at hand. Is there a common trick to lifting a value-level comparison to an `Ord` instance? The reverse is trivial --- it's `compare` --- but I can't see anything better than a |

| 2024-12-30 16:35:56 +0100 | <hellwolf> | how do you mean? quick fiddling turns out that Applicative ((,) a) not enough neither, since I need to bind the output. Anyways, raw lambda ftw for now. |

| 2024-12-30 16:32:00 +0100 | <hellwolf> | not sure if it's more readable code |
| 2024-12-30 16:31:52 +0100 | <hellwolf> | I read just recenlty (,) has an applicative that can do great things, now I think I can put it into practice |
| 2024-12-30 16:31:31 +0100 | <hellwolf> | this does though: Monoid a => Applicative ((,) a) |
