  // We'll call a specific method on the logger object, depending on the
  // severity passed in the original function call (if any). If there are
  // at least four arguments, a severity was passed. We check $arguments[3]
  // to ensure it's a valid severity constant, and if it's not, we default
  // to the notice() severity.
  //
  // @TODO Leave a FIXME for an invalid severity, since changing it to a
  // notice alters the intent of the original code.
