eval with chrome debugger support

gistfile1.js

function evalFromUrl(code, url) {
  // jshint evil:true

  // 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
  // Q: indirectEval?
  // A: Using the eval value rather than the eval keyword causes the
  //    code passed to it to be run in the global scope instead of the
  //    current scope. (Seriously, it's a javascript thing.)
  var indirectEval = eval;
  code = "(function(){"+code+"\n});\n//# sourceURL="+url+"\n";
  var program = indirectEval(code);
  program();
