* Python
Using the Microsoft language server as it's the best afaik. It's weird because it doesn't lookup the path to itself via PATH but has to be statically set.
#+BEGIN_SRC emacs-lisp
(use-package lsp-python-ms
:straight t
:hook (python-mode . (lambda ()
(require 'lsp-python-ms)
(envrc-mode)
(setq-local lsp-python-ms-executable (executable-find "python-language-server"))
(lsp)))

#+END_SRC
* C/C++
This just requires hooking lsp onto ~c-mode~ and ~c++-mode~.

* Haskell
Enable ~haskell-mode~, and ~lsp-haskell~
#+BEGIN_SRC emacs-lisp
(use-package haskell-mode
:straight t
:hook ((haskell-mode haskell-literate-mode) . interactive-haskell-mode)

Disable the ~haskell-stack-ghc~ flycheck checker, it's not used when lsp starts, but it does get loaded just before it. Loading and unloading it is slow and causes Emacs to freeze for a few seconds, so just disable it.
