How to wrap a raw string literal without inserting newlines into the raw string?

Question

I have a raw string literal which is very long. Is it possible to split this across multiple lines without adding newline characters to the string?

file.write(r#"This is an example of a line which is well over 100 characters in length. Id like to know if its possible to wrap it! Now some characters to justify using a raw string \foo\bar\baz :)"#)

In Python and C for example, you can simply write this as multiple string literals.

# "some string"
(r"some "
 r"string")

Is it possible to do something similar in Rust?

While raw string literals don't support this, it can be achieved using the concat! macro:

let a = concat!(
    r#"some very "#,
    r#"long string "#,
    r#"split over lines"#);

let b = r#"some very long string split over lines"#;
assert_eq!(a, b);
