print_message_token(Stream, Prefix, Token, Tokens)
User-defined hook method for printing a message token, declared in the
:ref:`logtalk apis:logtalk/0` built-in object as a public, multifile,
and dynamic predicate. It allows the user to intercept the printing of
a message token. This hook method is automatically called by the
:ref:methods_print_message_tokens_3
built-in
method for each token.
