Creating an EvalError

try {
  throw new EvalError('Hello', 'someFile.js', 10);
} catch (e) {
  console.log(e instanceof EvalError); // true
  console.log(e.message);              // "Hello"
  console.log(e.name);                 // "EvalError"
  console.log(e.fileName);             // "someFile.js"
  console.log(e.lineNumber);           // 10
  console.log(e.columnNumber);         // 0
  console.log(e.stack);                // "@Scratchpad/2:2:9\n"
