Unfortunately, you cannot drop in arbitrary expressions directly into the string literal. In the cases where we need to compute a complex value, we'll want to use `format_args!` directly. Due to specifics of the `rsx!` macro (which we'll cover later), our call to `format_args` must be contained within square braces.
