| 2026-01-15 19:04:15 +0100 | <geekosaur> | that seems pretty obvious to me, since as defined either associativity makes the "other" one a comparison on `Bool` |

| 2026-01-15 19:00:24 +0100 | <dolio> | Even though (==) is associative as an operation on Bool, Haskell will refuse to accept `x == y == z`. |
| 2026-01-15 18:58:05 +0100 | <dolio> | Not about whether how they're inserted matters. |
| 2026-01-15 18:57:54 +0100 | <dolio> | I expect the "associativity" in the question is not about that associativity. It sounds like it's asking about the rules on how parentheses are automatically inserted. |

| 2026-01-15 18:08:38 +0100 | <lambdabot> | Suggested fix: |
| 2026-01-15 18:08:38 +0100 | <lambdabot> | Variable not in scope: <=> |

| 2026-01-15 18:07:44 +0100 | <monochrom> | Alternatively, you can legalize "x == y == z" but you say it does not mean "(x == y) == z" or "x == (y == z)". You say it means "x == y && y == z". This is what mathematicians did. (You can trust that they are pros and they know what they're doing, right? Right? >:) ) |

| 2026-01-15 18:02:20 +0100 | <monochrom> | It is surprising but handy that both == and /= (xor) are commutative associative and with identities. |
| 2026-01-15 18:01:16 +0100 | <tomsmeding> | (because == on Bools is <=>) |
| 2026-01-15 18:00:56 +0100 | <monochrom> | (Fun fact: But if x,y,z are all Bool, then they are the same. Draw a truth table to see and be shocked. :) ) |
| 2026-01-15 18:00:07 +0100 | <monochrom> | "associativity" talks about whether "(x == y) == z" and "x == (y == z)" are the same or not. So those are the two expressions the hint wants you to look at. If they were the same, can you see a type error? |
