5.14.3 Word list example

The following example is from the garbage collector and uses wordlists to separate public words from helper words:

get-current ( wid ) vocabulary garbage-collector also garbage-collector definitions ... \ define helper words ( wid ) set-current \ restore original (i.e., public) compilation wordlist ... \ define the public (i.e., API) words \ they can refer to the helper words previous \ restore original search order (helper words become invisible)
