commit c6ef03699ce493b39b010f39863c80370bccf0d5
Author: Gordon Ball <gordon at chronitis.net>
Date:   Fri Apr 6 11:34:20 2018 +0000

    Patch syntax which causes a buble error
    
    While this works with the package-specified rollup at 0.41 and
    rollup-plugin-buble at 0.15, as of the current debian versions (0.50 and
    0.19 respectively), this destructuring assignment causes an error.
    
    This patch simplifies the syntax so no transform is required.
