As someone working on a larger Nim codebase, this! Especially if it can be used to improve Nimsuggest. I'm willing to pitch in on helping with Nimsuggest too if possible. It seems like better LSP would overlap with REPL as well? I also believe a new C/C++ backend will take a while to work out the inevitable kinks, whereas IC, view types, etc will be much quicker to get to a usable state.
