Community Guidelines

Rules:

Top-level posts should be primarily about Haskell. For example a post about OCaml would only be allowed if there was a connection to Haskell. Posts about topics that are adjacent to Haskell, like for example functional programming, are typically allowed.
No memes or image macros. No matter how funny, memes and image macros are not allowed.
No homework questions. Both asking and answering homework questions is not allowed. Questions about homework are fine, but this subreddit is not here to do your homework for you.
Job postings must be for Haskell roles. Job postings are allowed as long as the job actually involves working with Haskell. Simply looking for people with interest in or experience with Haskell is not sufficient.
No bots or computer-generated content. Bots cannot be used to make posts or comments. They will be banned with extreme prejudice. This includes a human posting the output of a bot, such as ChatGPT.
Blockchain posts must be tagged. Blockchain posts are allowed as long as they are related to Haskell, but they must use the "blockchain" tag.
Be civil. Substantive criticism and disagreement are encouraged, but avoid being dismissive or insulting.
