| 2024-10-18 13:00:25 +0200 | <tomsmeding> | and at that point you also evaluate the argument to id |
| 2024-10-18 13:00:14 +0200 | <tomsmeding> | "id' = id" is true because sure, id' is strict in its argument, but that strictness only comes into play if you actually use the result of the id' call |

| 2024-10-18 12:59:38 +0200 | <tomsmeding> | id = force is not true, but is true in the world of "total haskell" |

| 2024-10-18 12:59:20 +0200 | <tomsmeding> | id' = id is actually true |
| 2024-10-18 12:59:04 +0200 | <Inst> | but in general, we pretend that id' = id, or for that matter, let id'' = force, then again, force has an NFData constraint |

| 2024-10-18 12:57:51 +0200 | <Inst> | the mystery is still, if you have in a let or where cluase, an unknown value, you can bang it and still get evaluation |
| 2024-10-18 12:56:39 +0200 | <Inst> | :( |
| 2024-10-18 12:56:27 +0200 | <tomsmeding> | ah, except of course when it doesn't because pattern matching is more complicated |
