Turn email into a code editor

Linking to a Gist seems evil to me since i make thorough (searchable) backups of my email (which would contain the code) whereas the Gist may or may not be available in a few years time.

As far as highlighting goes, i'm a neckbeard who uses mu4e, so i can load up paredit mode if i want nice editing features in my compose-email pane.

Having said that, i guess there are people for whom this is still a problem in 2014. On the other hand, i'd be unhappy if somebody sent me HTML email containing "highlighted" code.

I can't think of any reason why you wouldn't just email a link to a gist. It's bad enough having information sitting in emails rather than a properly organised structure, but at least that problem is solved for code. Isnt this a step backwards?

That FizzBuzz-code is wrong, it does 101 iterations (0-based for loop).
