If the Literal prettyprinting protocol is insufficient, a method can be defined to control prettyprinting directly:

pprint* ( obj -- )

Some utilities which can be called from methods on pprint*:

pprint-object ( obj -- )

pprint-word ( word -- )

pprint-elements ( seq -- )

pprint-string ( obj str prefix suffix -- )

pprint-prefix ( word quot -- )

Custom methods defined on pprint* do not perform I/O directly, instead they call prettyprinter words to construct sections of output. See Prettyprinter sections.
