| 2024-11-14 23:48:37 +0100 | <carbolymer> | thanks geekosaur. I've found some resources on tf vs fd: |

| 2024-11-14 23:45:53 +0100 | <geekosaur> | (aside from the big one, that ghc isn't going to get actual type lambdas that way possibly ever) |
| 2024-11-14 23:45:32 +0100 | <jackdk> | I had hoped that there was a decent idiom for writing a type family that could compute z from `class Foo x y z | x y -> z` but nobody could tell me one |

| 2024-11-14 23:45:19 +0100 | <geekosaur> | does this mean there are still some issues with tyfams? |
| 2024-11-14 23:45:01 +0100 | <geekosaur> | huh |
| 2024-11-14 23:44:44 +0100 | <geekosaur> | I mean, we've already ditched backward compatibility in so many other ways, anyone who wants to stay with mtl+fundeps can keep using mtl2 |
| 2024-11-14 23:44:30 +0100 | <jackdk> | Just yesterday I wanted to turn a relation expressed in fundeps into a type-family-shaped thing and the best suggestion I got was "don't, pick over the type using generics instead" |

| 2024-11-14 23:43:48 +0100 | <geekosaur> | …but that was over a decade ago. maybe it's time for mtl3: the type families edition |
| 2024-11-14 23:43:10 +0100 | <geekosaur> | (and maybe a performance issue) |
| 2024-11-14 23:42:52 +0100 | <geekosaur> | (IIRC there were a few problems with type families back then that meant the mtl folks went with monads-fd, including a bug in older ghcs) |

| 2024-11-14 23:41:52 +0100 | <geekosaur> | I do sometimes wonder what the Haskell ecosystem would look like now if monads-tf had won out over monads-fd as the successor to mtl1 |

| 2024-11-14 23:40:56 +0100 | <shapr> | yeah, just curious what you thought |
| 2024-11-14 23:40:45 +0100 | <geekosaur> | I'm not sure they're more principled, since I'm not really a type theory or type level wonk |
| 2024-11-14 23:40:32 +0100 | shapr | thinks about that |
| 2024-11-14 23:40:22 +0100 | <geekosaur> | I think in some sense they fit Haskell better, because fundeps are a chunk of Prolog imported into the type system |
| 2024-11-14 23:39:47 +0100 | <shapr> | geekosaur: do you think type families are more principled? |
| 2024-11-14 23:38:08 +0100 | <geekosaur> | many people consider the latter mroe principled, but functional dependencies have been around longer and most standard libraries still use them |
| 2024-11-14 23:37:39 +0100 | <geekosaur> | they are, and yes, they're essentially identical. one uses a functional dependency to establish a relationship between types, the other a type family that is associated with the typeclass ("associated type family") |

| 2024-11-14 23:12:41 +0100 | <carbolymer> | what's the difference between Foo1 and Foo2 here: https://paste.tomsmeding.com/HEZo1ic4 ? aren't they expressing the same thing basically? |
