    You can you typed holes with HLS, but sometimes there are performance issues:
  • [ANN] Pre-release VSCode-Haskell 2.0.0
    3 projects | | 5 Apr 2022
    The major issue is related to Template Haskell. If you use the current HLS releases, you notice the message "This binary is not built with Template Haskell support". We added this message because the way static binaries work is just not cross-plattform. What might work on ubuntu, doesn't reliably work on other distros. This lead to a number of dynamic linking issues, impossible to understand error messages and many more. See for example this:

    The releases page has macOS-9.2.1 but that's Intel, and it has aarch64- but that's GHC 8.

    It’s almost supported in Haskell Language Server now too- follow for it ^^
