See swift grammar, SE-0200 blog post

Apparently, #"Hello"# is a legal way of delimiting strings in Swift 5. This is similar to Rust's raw string syntax, in that the opening and closing # must be matched, but differs in a few important ways such as interpolation.

Unfortunately, this might have to live in externals, like the Rust implementation does. I'm not sure how that could be done and still handle interpolation.

        return #"<a href="\#(absoluteString)">\#(title)</a>"#
    }
}
```
