Agree. I don't want the language to start looking like rust.

Sorry, but what is unreadable? A specific proposal? Or the website?

The color choice is bad, that makes it difficult for my eyes to read. In case you hadn't realized each line is a link to the actual proposal. That's where the detail is found. The error line in the page tries to summarize the proposals way of handling errors. Common techniques are put in groups. I though it was pretty concise.
