{ $description { $link t } " if the call is flushable. To be flushable, two conditions must hold; first the word must have been declared flushable. Then, if it has any \"input-classes\" declared, all inputs to the word must fit within those classes. For example, if an input is a " { $link string } " and the declared input class is " { $link integer } ", it doesn't fit and the word is not flushable." } ;
