example suggestion: Multi-line comments

[Anton-4]

There is no multi-line comment syntax in Roc, you'll need to use # before every line. This is necessary to allow roc programs to be used as bash scripts. Most editors allow you to comment several lines at once using a shortcut like Ctrl+/ on vscode.

It's a bit strange to have an example that basically says "there is no multi-line comment syntax" but I think it's useful when searching for answers.
