=={{header|Quackery}}==

A Quackery word can take a variable number of items from the stack, either by specifying the number of items on the top of stack, or by placing a marker on the stack underneath a number of items.

(<code>oats</code>: "'''o'''ne '''a'''nd '''t'''he '''s'''ame" compares the ''identity'' of two items, ensuring that <code>marker</code> is uniquely identified.)
