eval-ish strip comments from js hash string to valid js object `ala unstrict JSON.parse()`, useful for json configuration files where you want to enable comments.

hashStr2json.js

function hashStr2JSON (str) {
  try {
     return Function('return ' + str)();
  } catch(e) {
    // something goes wild
    throw new Error('Could not parse hash because of:  ' + e.toString())
  }
  }

var jsonfromhash = hashStr2JSON('{a:/*comment*/"b"}//comment'); // read hash string, it will also work with multiline files

This may cause XSS attack, is there any more safely way ?
