| 2024-09-30 17:31:00 +0200 | <ski> | if you only applied it to an `a', getting a `[Tree a] -> Tree a' back, the container hasn't been created yet, so you can't match to extract things from it |
| 2024-09-30 17:30:22 +0200 | <ski> | think of `Node :: a -> [Tree a] -> Tree a' as a function that takes an `a', returning a new function that takes a list of trees of `a's, and *then* constructs an aggregate compound that contains/holds these two items, for later retrieval |
| 2024-09-30 17:30:07 +0200 | <Inst> | is that why, since if / case compiles to case foo of True; False in core |
| 2024-09-30 17:29:43 +0200 | <Inst> | iirc function equality is a complete nightmare to deal with |
| 2024-09-30 17:29:17 +0200 | <Inst> | or in other words, why? |
| 2024-09-30 17:28:58 +0200 | <ski> | yes |
| 2024-09-30 17:28:39 +0200 | <Inst> | or in other words, haskell can only match on fully applied data constructors |
| 2024-09-30 17:27:54 +0200 | <ski> | `False' is a data constructor that is not a function |
| 2024-09-30 17:27:40 +0200 | <ski> | (and using `Left {}' doesn't help with this) |
| 2024-09-30 17:27:30 +0200 | <Inst> | yeah I thought it was a weird exception that'd allow me to match on functions since data constructosr are functions |
| 2024-09-30 17:27:17 +0200 | <ncf> | consider foo @Bool (bool (Left True) (Right False)) |
| 2024-09-30 17:27:15 +0200 | <ski> | yea, that too |
| 2024-09-30 17:27:01 +0200 | <ncf> | your match isn't complete, if anything |
| 2024-09-30 17:26:52 +0200 | <ski> | each data constructor pattern must be a data constructor fully applied to patterns corresponding to all the component arguments of the data constructor |
| 2024-09-30 17:26:20 +0200 | <Rembane> | Inst: Try Left{} instead |
| 2024-09-30 17:26:07 +0200 | <ski> | you can't match on functions with data constructors |
| 2024-09-30 17:25:54 +0200 | <Inst> | should Haskell accept this? |

| 2024-09-30 17:23:54 +0200 | <Inst> | why doesn't Haskell accept this? |

| 2024-09-30 16:03:54 +0200 | <opqdonut> | Guest9426: https://haskell.mooc.fi is a fairly up-to-date course on the basics |

| 2024-09-30 16:02:05 +0200 | <Guest9426> | Can someone recommend a good learning resource to start learning haskell since there seems to be way too many to choose from and a lot of them might be outdated |
