`@format` replaces IIFE blocks with content hash

[farism]

component Main {
  fun render : Html {
    let {result, code} =
      @format {
        let iifetest =
          () {
            `
            (() => {
              // ...
            })()
            `
          }

        ""
      }

    <pre>
      <{ code }>
    </pre>
  }
}

will result in

let iifetest =
  () {
    `6e915ffb5b7723d0ddb6fed455221832`
  }
