Corrupt exception object

[rakudrama]

I expect the attached program to run without assertion with --enable_type_checks

Something throws an exception, but the exception's toString method throws a secondary exception. It appears that code is missing from the NoSuchMethodException constructor - there is no _arguments property.

function $toDartException(e) {
  ...
      } else {
          // TODO(jmesserly): can this ever happen?
          res = new NoSuchMethodException('', e.arguments[0], []);
  ...
}

// ********** Code for NoSuchMethodException **************
function NoSuchMethodException() {}
NoSuchMethodException.prototype.toString = function() {
  var sb = new StringBufferImpl("");
  for (var i = 0;
   i < this._arguments.length; i++) {
    if (i > 0) {
      sb.add(", ");
    }
    sb.add(this._arguments.$index(i));
  }
  sb.add("]");
  return ("NoSuchMethodException - receiver: '" + this._receiver + "' ") + ("function name: '" + this._functionName + "' arguments: [" + sb + "]");
}

I just hit this again. The bug makes it difficult to generate succinct test cases for other problems.

Moving this to high priority to reflect Stephen's comment that this is blocking other work. I propose that we start using these priorities in this way when filing bugs as well to help identify those that need to be addressed sooner.
