I'd love to see syntax highlighters (like Pygments), editors and IDEs, autocompletion providers, debuggers, and all other language-related tooling consume a standardized canonical "language description format". Making a new language? Bam! It's automatically supported by Visual Studio, Eclipse, Emacs, vim, Sublime Text, gdb, Pygments, the list goes on.

The extension capabilities are also awesome. Let's say I have a huge project and, at a certain level of abstraction, users aren't allowed to use fprintf(stderr, ...), they need to use LOG(...). It would be great to have a file in your project that can tell your environment to give you the "red squigglies" and autofix information for such situations.

Take our product: we have javascript, typescript, XML and SQL stored in strings in our C# codebase. As you can expect, these are really hard to maintain, and just has hard to move to separate templates.

Oh, did I mention that we also have our own templates, our own DSL, handlbar templates, jQuery templates and templates used in various libraries.

Nitra can support that all in one tool.

Easier to make a DSL => Wider adoption of new languages => Better grounds for experimentations => Much more creative stuff => More accessible technology
