| 2025-01-08 11:22:38 +0100 | <tomsmeding> | are you sure you're not looking for Data.Vector.Storable.Mutable? |

| 2025-01-08 11:20:29 +0100 | <tomsmeding> | and also, the 'a' here is a boxed type |
| 2025-01-08 11:20:10 +0100 | <tomsmeding> | but unboxed types in an unboxed vector (as opposed to a _storable_ vector) are stored in struct-of-arrays format |
| 2025-01-08 11:19:31 +0100 | <tomsmeding> | recall my earlier comments on the ghc unboxer |
| 2025-01-08 11:19:20 +0100 | <tomsmeding> | are you sure you need that for performance? |

| 2025-01-08 11:07:16 +0100 | <haskellbridge> | <magic_rb> is there no way to directly read from a Unboxed Mutable Vector using Int# as the index and read the undoxed type directly? https://hackage.haskell.org/package/vector-0.13.2.0/docs/Data-Vector-Unboxed-Mutable.html i dont see anything in the module |

| 2025-01-08 10:05:14 +0100 | <monochrom> | But the paper doesn't contain such advanced examples. All examples are basically natural transformations like "oh rev is a natural transformation". Those don't need arbitrary relations, just functions. |
| 2025-01-08 10:03:59 +0100 | <monochrom> | But if you replace Maybe by the System F encoding, i.e., prove that e :: forall a. forall b. b -> ((a -> a) -> b) -> b has only two possibilities, that will require you to use a non-function relation for b. |

| 2025-01-08 10:02:00 +0100 | <monochrom> | Err, that one still works with a function relation. |
| 2025-01-08 10:01:00 +0100 | <monochrom> | Sometimes you really want to use a non-function relation, e.g., when proving that e :: forall a. Maybe (a->a) can only be Nothing or Just id. |
