I'm planning to update and refresh Opaleye's documentation and add some new functionality for common use cases. To help with this I'd like to request input from anyone who has ever tried the library.
Specifically, what do you (or did you) find hard about using Opaleye and what did you dislike about it? If you tried it and gave up, what was the major sticking point?
I dislike the whole `Default` type class stuff and have a very hard time reasoning about what is going on behind it. I understand it's basically creating "n-ary structures" (the description is as vague as my understanding), but I still struggle with it.
Hi Ollie, Thanks for the feedback. Have you read the "Default Explanation" document? https://github.com/tomjaguarpaw/haskell-opaleye/blob/master/Doc/Tutorial/Def... Does that help you understand what's going on behind Default? Is there still something missing that could help your understanding? Tom
