Luke Boswell (Nov 24 2023 at 22:59): Luke Boswell (Nov 24 2023 at 22:59):I'm opening this thread because I think it would be really useful if someone is able to contribute to this issue for AoC. I think it would help newcomers to have a nicer experience with handling errors when writing programs using basic-cli or basic-webserver.
Here is the previous zulip discussion, and this is the GH Issue for it.
Ayaz Hafiz said:
it's because
Task.Taskis an opaque type, and not all tag unions can be open-by-default-in-output position under an opaque type (but type parameters like the tags here should be). I'll file an issue, but in the meantime you can work around this by saying[ZeroArgsGiven]_and[ReadFileErr Str]_.
I asked Ayaz and he mentioned that this should be straightforward to fix. I'm hoping we can discuss it here and someone might volunteer to fix it.
