dotfiles VS StaticLint.jl

You can find my setup here. Yes, the autocomplete is good enough for my purposes. I don't use VSCode so can't compare - but I've got autocomplete running in Emacs and it mostly behaves as I would expect. Keep in mind that LanguageServer.jl is still under development, so some autocompletion fails fundamentally because of the backend - in other words, some things currently won't work in any editor, I think.

Yes, tooling around this is being developed in the form of linters (e.g. https://github.com/julia-vscode/StaticLint.jl) and through real compiler integration tools like the very cool https://aviatesk.github.io/JET.jl/dev/ but this is definitely somewhere that the tooling in julia is weaker than in other languages. It seems to be picking up a lot of speed though.

It is correct if `A` is of type `Array` as normal Array in julia has 1-based indexing. It is incorrect if `A` is of some other type which subtypes `AbstractArray` as these may not follow 1-based indexing. But this case errors normally due to bounds checking. The OP talks about the case where even bounds checking is turned off using `@inbounds` for speed and thus silently giving wrong answers without giving an error.

An issue was created sometime ago in StaticLint.jl to fix this: https://github.com/julia-vscode/StaticLint.jl/issues/337

Statically lint = find errors in the Julia file like using variables that are not defined, and functions with the wrong arguments. For Julia, StaticLint.jl is an actively developed library that does static linting. It basically provides a bunch of functions that spit out errors in your Julia file like those that I mentioned above. If you are an Emacs editor user, this project is like a "convenience" which will run Julia silently in the background, and communicate with it to extract errors in the file that you currently have open. These errors are then highlighted in your editor view using the Flycheck package that is one of the ways to highlight errors in Emacs.
