2024-11-13 02:03:08 +0100 <Axman6> bailsman: that feels like you're reinventing https://hackage.haskell.org/package/vector-0.13.2.0/docs/Data-Vector.html#v:imap? or something else? I think what you've written will have to repeatedly freeze and copy the vector so it's going to be very slow.

2024-11-13 02:06:53 +0100 <Axman6> Even if things aren't being copied, you're incurring a bounds check for every index. mapM (pure . f) v would be much more efficient, and more idomatic (it took me ages to figure out what that code was actually doing)

2024-11-13 15:15:30 +0100 <tomsmeding> Hecate: not replying to the email because I'm not a ghc expert but iirc GHC uses a bumping allocator, so if you allocate a bunch of heap nodes right after each other, they will end up adjacently in memory. So you get memory locality, but still pointers.
2024-11-13 15:16:43 +0100 <tomsmeding> Furthermore, if there aren't any pointers into tail elements of your list, the GC will always traverse the list from head to tail. If you use the copying GC (i.e. not --nonmoving-gc), then it will (I think!) copy values in order of visiting them, so even if the list wasn't packed beforehand, they will be anyway after a GC pass.
2024-11-13 15:17:01 +0100 <tomsmeding> I think this is what you were referring to in your original email

2024-11-13 17:36:08 +0100 <EvanR> according to wikipedia "code points in the Private Use Areas are not noncharacters, reserved, or unassigned". By classical logic, not non-characters implies "character" xD. Later it quotes standard talking about characters which are assigned code points in the private use area. So there might actually be characters involved, but haskell has no way to know what they are

2024-11-13 19:40:03 +0100 <bailsman> Can it make sense to encapsulate a mutable vector in a state transformer monad whose version of runState internally does something with runST? That way the 'pure world' doesn't really need to know or care how you implemented things internally. You just get an interface against which you can do defined operations on the monad.
2024-11-13 19:40:31 +0100 <bailsman> The one thing I find "concerning" is that this means every function that operates on your data is inside your monad, but maybe that's just good and proper and how things are done.
