| 2024-11-16 22:37:26 +0100 | <int-e> | you'll either have to hide the import or use qualified names if you want to use such a function though |
| 2024-11-16 22:36:11 +0100 | <geekosaur> | correct, because they're not defined within the same module/scope. |
| 2024-11-16 22:34:59 +0100 | <hellwolf> | Overlapping function names from Prelude does not generate warnings, it seems acceptable? |

| 2024-11-16 22:01:06 +0100 | <hellwolf> | I think I found a solution, maybe it is common for eDSLs: say I have a keyword "match", I just need to do (BlockArguments alert) `match a \case -> Maybe a' -> a'; Nothing -> some_def`, where by a just needs to be constrained by an imaginary "EnumerablePatternMatchingCases", such that the codegen can just enumerate through the cases and generate code for all branches accordingly. |
| 2024-11-16 21:55:51 +0100 | <geekosaur> | especially in Haskell, because that is strict by default and therefore drives evaluation |
| 2024-11-16 21:54:11 +0100 | <geekosaur> | but yes, the base assumption is pattern matching on constructors |
| 2024-11-16 21:53:26 +0100 | <geekosaur> | this is alos why MukltiWayIf has the syntax it does, since the conversion to such a case with multiple guards is trivial |
| 2024-11-16 21:52:51 +0100 | <geekosaur> | `if` normally becomes a guard in a dummy `case` (`case () of () | …`) |
| 2024-11-16 21:52:20 +0100 | <hellwolf> | Without, you may emulate with if isConstructorA a then .. else if isCOnstructorB .. and so on. |
| 2024-11-16 21:51:33 +0100 | <hellwolf> | Maybe a bad formulation of the question. I guess ADT by definition needs pattern-matching/case analysis. |

| 2024-11-16 21:50:04 +0100 | <hellwolf> | Is the advantage of case/pattern matching, over the if-then-else chains, in its ability to do exhaustiveness checking? |

| 2024-11-16 21:46:23 +0100 | <geekosaur> | but where Haskell-level `let` defaults to lazy pattern matching, in STG it's strict |
| 2024-11-16 21:45:49 +0100 | <geekosaur> | well, actually, slight lie. `let` does pattern matching, and by the time you reach STG `case` has become `let` |

| 2024-11-16 21:41:02 +0100 | <geekosaur> | there is some desugaring of `case` because nested patterns aren't supported by Core or lower levels, but in the end it's still `case` |
| 2024-11-16 21:40:15 +0100 | <geekosaur> | `if` is syntax sugar |
| 2024-11-16 21:40:05 +0100 | <geekosaur> | `case` is primitive (and in fact goes all the way down to STG) |

| 2024-11-16 21:37:54 +0100 | <hellwolf> | Do I have to forego the case expression for this embedded language? |
| 2024-11-16 21:37:00 +0100 | <hellwolf> | "Conditionals (e.g. “if e1 then e2 else e3”) means “ifThenElse e1 e2 e3”. However case expressions are unaffected." -- what, is actually a case expression, then? |
