| 2024-12-29 03:27:53 +0100 | <Leary> | This is clearer when looking at a corresponding indexed applicative: `unit :: f i i (); fuse :: f i j a -> f j k b -> f i k (a, b)` |

| 2024-12-29 03:24:00 +0100 | <Leary> | thirdofmay: The Atkey indexed monad has two indices for the same reason `Category` arrows do; its bind performs a kind of composition. Simple examples include the indexed writer monad, which writes category arrows rather than monoids, and the indexed state monad which has distinct types for the initial and final state. |

| 2024-12-29 02:36:55 +0100 | <hololeap> | ok I think I see what you mean |

| 2024-12-29 02:32:11 +0100 | <ncf> | i.e. applicative functors are monoids in the category of endofunctors *with Day convolution as the monoidal product* |
| 2024-12-29 02:31:34 +0100 | <ncf> | well that doesn't tell you which monoidal structure you put on it |
| 2024-12-29 02:31:29 +0100 | <hololeap> | (I barely understand this stuff so don't take me too seriously) |
| 2024-12-29 02:30:10 +0100 | <hololeap> | isn't that usually just referred to as "the category of endofunctors" |
| 2024-12-29 02:28:29 +0100 | <ncf> | i.e. the endomorphism monoidal category on Set in the bicategory of categories |
| 2024-12-29 02:27:24 +0100 | <ncf> | composition of endofunctors |
| 2024-12-29 02:27:14 +0100 | <ncf> | with composition as the monoidal product |
| 2024-12-29 02:26:37 +0100 | <hololeap> | "with composition" seems like it would be redundant. isn't that implied by it being a category? |

| 2024-12-29 02:23:42 +0100 | <ncf> | (the one that monads are just monoids in) |
| 2024-12-29 02:23:31 +0100 | <ncf> | i guess the one-sentence definition of an indexed monad is "category enriched in the monoidal category of endofunctors with composition" |

| 2024-12-29 01:42:05 +0100 | <ncf> | there's some motivation here https://stackoverflow.com/questions/28690448/what-is-indexed-monad |
| 2024-12-29 01:40:41 +0100 | <ncf> | are you thinking of exofunctors or something |
| 2024-12-29 01:40:15 +0100 | <geekosaur> | maybe I'm completely confused, that was what I thought (part of) the point of it was |
| 2024-12-29 01:38:30 +0100 | <ncf> | geekosaur: i don't think Set is an indexed monad? |
