| 2025-01-15 17:07:23 +0100 | <tomsmeding> | in haskell the proof could be `undefined` |
| 2025-01-15 17:07:19 +0100 | <pounce> | the only inhabitants of a = a are generated by refl. there's no bot |
| 2025-01-15 17:07:16 +0100 | <tomsmeding> | right, that's a thing in agda |
| 2025-01-15 17:06:57 +0100 | <pounce> | you don't need to 'use' the proof |
| 2025-01-15 17:06:52 +0100 | <Leary> | It's /statically/ verified. Haskell's `Refl` requires pattern matching for soundness only because it's lifted. |
| 2025-01-15 17:06:50 +0100 | <pounce> | tomsmeding: if you have an inhabitant of the equality proof then it already holds |

| 2025-01-15 17:06:25 +0100 | <tomsmeding> | but how can an equality proof be erased if you're depending on it to hold? |
| 2025-01-15 17:05:46 +0100 | <pounce> | i _think_ so. i usually use --without-k which doesn't allow all dot patterns for equality |
| 2025-01-15 17:05:06 +0100 | <tomsmeding> | pounce: if you pattern-match on a Refl in agda, can you still mark that argument as erased? |
| 2025-01-15 17:04:50 +0100 | <tomsmeding> | a zero-bit equality is just ensuring that there's no unnecessary runtime overhead in reifying the proof, whereas an erased equality is praying that the proof would have also held in production |
| 2025-01-15 17:03:56 +0100 | <tomsmeding> | Leary: but surely an erased equality is not quite the same as a zero-bit equality? |
| 2025-01-15 17:03:23 +0100 | <Leary> | tomsmeding: See this thread for a few examples: https://discourse.haskell.org/t/unboxed-equality/9929 |
