lua is such a nice and sane language for application config. I really enjoy neovim's choice to use it, and with this release more or less allow 100% of typical configuration to be done entirely in lua. Good riddance to bespoke scripting languages.
It's also so much easier to write plugins in Lua than the insanity that is Vimscript. It's why I'm slowly moving into Lua-ifying my configuration away from old standbys like NERDTree to things like nvim-tree.lua.
