It's awesome that you figured out how to get that syntax to work!

Unfortunately svelte-preprocess can't use a patched Coffeescript compiler, at least not by default, as that would be quite surprising for users and would require on-going maintenance to make sure nothing breaks as the compiler changes.

I'm sure people looking to use reactive statements would use your patch, though.

I modified the code so that the :label syntax is enabled only when the label:true argument is passed. So we don't break compile.

    svelte(
      preprocess: [
        sveltePreprocess(
          coffeescript: {
            label:true
            sourceMap: true
          }
          stylus: true
          pug: true
        )
      ]
    )

Thanks for the contribution and the idea! However, as @mrkishi said,
