| 2026-04-07 11:12:02 +0000 | <ski> | i think there's some tool to look for potential problems with partial operations (of which `undefined' is a blatant case), but i forgot the name, gentauro |
| 2026-04-07 11:11:20 +0000 | <ski> | another example. you can e.g. make a type `Expr var', for representing some kind of expressions, where `var' is a type of free variable identifiers. in that case, `Expr Void' means an expression with no (free) variables |
| 2026-04-07 11:10:54 +0000 | <gentauro> | ski: is there a way to "enforce" non-usage of `undefined` in a code base? |
| 2026-04-07 11:09:53 +0000 | <ski> | so, i changed to `endThread :: M Void' and `forkThread :: M Void -> M ()', which allowed me to confidently then remove the `undefined's |

| 2026-04-07 11:09:12 +0000 | <ski> | .. i did a cooperative concurrency monad thing, where i could fork off a (user-level) thread. i wanted the spawned thread to always end by invoking an operation `endThread'. at first (iirc) i used `endThread :: M a' and `forkThread :: M a -> M ()', but i had some `undefined's sprinkled through the implementation of the operations, which i wanted to remove |
| 2026-04-07 11:06:07 +0000 | <ski> | but, then you'd need to use `void' above (called `absurd' in `Data.Void'), to be able to invoke it in any context, e.g. in a branch that should abort, while another branch returns some value of some particular type (distinct from `Void') |
