| 2026-04-21 19:11:28 +0000 | <haskellbridge> | <ijouw> Oh yes, I thought the Maybe was the outside m |
| 2026-04-21 19:10:33 +0000 | <dutchie> | but that prints hi and there for me before getting Just 'c' |

| 2026-04-21 19:09:02 +0000 | <haskellbridge> | <ijouw> In my understanding that should not matter for lists. |

| 2026-04-21 19:06:24 +0000 | <dutchie> | hmm, is sequence running all the actions even when there is a Just though |

| 2026-04-21 18:59:57 +0000 | <dutchie> | I often end up writing `maybe action pure` and feeling like I'm missing something there as well |
| 2026-04-21 18:58:45 +0000 | <dutchie> | `fromMaybe (h x) . asum =<< sequence [f x, g x]` spreads the xs around enough that it's not offending me too much |
| 2026-04-21 18:58:05 +0000 | <dutchie> | so `f, g :: Foo -> m (Maybe Bar)` |
| 2026-04-21 18:57:41 +0000 | <dutchie> | I have now further complicated matters by realising that f and g are actually in my effect monad |
