Microsoft Edit is fully written in Rust. And the source-code is actually fully open-source as well under MIT license 😮.
I personally would like see them calling it dos-edit or just dosedit, since that would be kinda funny. But I understand it will be called ms-edit instead.
I know Linux already has vi, vim, neovim and nano, ... and more... However is kind of ironic to see this binary be shipped to Linux distros. Of course it's already added to Arch btw: https://aur.archlinux.org/packages/ms-edit-git
