Oh snap. Nerd stuff here with @GabriellaG439 (of #Haskell and #Nix fame) on the Impure Pics @impurepics channel, where she talks about #Grace, which looks like a web-based functional language (I just started the video and got excited)

I wanted a #Haskell function to efficiently compute the conjugate of an integer partition. I think I know how to write it, but it's fiddly. There's a nice, succinct functional specification:

conjugate = reverse . map length . transpose . map (`replicate` ())

but it's slow. Now I'm wondering whether it's possible to derive an efficient version from this specification, #Bird-Meertens style. Anyone know of previous work along these lines? Or should I add it to my list of interesting projects?

"Exception Annotations: Lay of the Land" by Edsko de Vries.

TL;DR: Use ghc 9.12, don’t call throwIO on an argument of type SomeException, and use your own function instead of displayException if you want to see all exception annotations.
