  17 // If a variable referenced in the value, sender or @index clause is a lazy or fuzzy
  18 // variable, the expression assigned to this variable is equal to the result produced
  19 // by the trigger operation i.e. later evaluation of the lazy or fuzzy variable does not
  20 // lead to repeated invocation of the trigger operation.
