Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://cpb.gitbook.io/book/languages/haskell/disadvantages.md). # Disadvantages ## Bad stuff about Haskell, but who cares, because it's cool * For some, that stuff like <:> >>= <=< @>-,-'--() in every line can be annoying * Some people are going mad when they see all the possible ways to write out the same thing * Tooling is limited, awkward and slow * Library quality and coverage is inconsistent, you can't easily do UI development and machine learning with Haskell, lack of libraries * If you don't have a beefy PC, don't even try to compile Haskell code, you're gonna probably be faster a fossil fuel than your crappy PC will compile your code, just loading modules into GHC can take almost half a minute --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cpb.gitbook.io/book/languages/haskell/disadvantages.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
