Hy Programming Language Enhancements For Automation And Ide Support

The article highlights updates to the hy programming language, introducing features such as automatic reloading and enhanced exception handling. These modifications allow hy to be utilized as an automation tool and overcome constraints with expression wrapping. The improvements also benefit IDE support, particularly in Vim, Emacs, and Neovim’s Nelean plugin.
