Have you ever tried Atom? Its interface is written in HTML5 + CoffeeScript, and it targets CoffeeScript as the primary language. Tell the GitHub guys about tooling...

But besides, judging a language based on available tooling is akin to judging a CPU based on the computer casing looks.

For a real programmer, GNU Nano with appropriate highlighting should be enough. If a language calls itself "high-level" but makes the coding process hard without tooling, it deserves no attention at all.

A real programmer makes mistakes, and a real programmer automates tasks. That's what programmers are for.
