2025-12-03 17:37:06 +0100 <tomsmeding> (it's a 2x improvement when called many times, at the cost of a 10% slowdown when called once)
2025-12-03 17:36:45 +0100 <tomsmeding> but I'll just have to live with that I suppose :)
2025-12-03 17:36:33 +0100 <tomsmeding> the downside is that that makes performance slightly worse if the function is only called once
2025-12-03 17:35:53 +0100 <Leary> `NOINLINE` it is, then.

2025-12-03 17:35:27 +0100 <tomsmeding> Leary: doesn't seem to; they were already in a separate lambda (within a 'let' that defines the shared binding), but adding a ! doesn't seem to help

2025-12-03 17:34:05 +0100 <Leary> tomsmeding: Does it work if you push the latter args into lambdas and bang the shared binding?
2025-12-03 17:33:37 +0100 <Lycurgus> i couild expand as a very rude name of this category of quety has occured to me but being a real person i know better

2025-12-03 17:32:55 +0100 <tomsmeding> well, presumably something is relevant here, yes
2025-12-03 17:32:45 +0100 <Lycurgus> nor "nuthin"?
2025-12-03 17:32:33 +0100 <tomsmeding> (I don't see how TH is relevant here)
2025-12-03 17:31:22 +0100 <tomsmeding> I can force GHC to do what I want by making the "inner function" NOINLINE (at which point the (inlined) "outer function" does the proper sharing), but that feels like a hack
2025-12-03 17:31:20 +0100 <Lycurgus> wo TH or nuthin i presume
2025-12-03 17:30:50 +0100 <tomsmeding> I have some data that I can already compute based on only the first argument that I would like to share over multiple calls that have the same first argument, and GHC isn't doing it
2025-12-03 17:30:19 +0100 <tomsmeding> can I override GHC's arity analysis to force a particular function to have lower arity than GHC would otherwise infer?

2025-12-03 17:04:56 +0100 <tomsmeding> but the fact that you're asking about a list suggests you have no such ordering :)

2025-12-03 17:04:39 +0100 <tomsmeding> __monty__: if the values have a well-defined ordering, a binary tree will give you O(log(n)) insertion instead of O(n)

2025-12-03 16:52:21 +0100 <__monty__> In my case the extra structure isn't necessary.

2025-12-03 16:51:37 +0100 <Leary> __monty__: In that case, why flat? It really sounds like you want a heap or a set.

2025-12-03 16:50:30 +0100 <kuribas`> __monty__: folds are isomorphic to a list
2025-12-03 16:50:26 +0100 <__monty__> I'm open to suggestions for a data structure for the specific case of pushing a value into the flat structure from the front and stopping when the value being pushed is smaller than the next. Think of a row of marbles, the first marble smaller than the one pushing against it falls out.

2025-12-03 16:49:33 +0100 <Leary> Well, if you want to drop any elements. Maybe `Traversable` is enough if you don't.
2025-12-03 16:48:12 +0100 <Leary> `Witherable`, probably.
