The representation type of pretty-printable documents.

Indentation is expressed as integer space units.
The final layout of a document as a string.
Interface for pretty-printable values.

implementation
just uses the value
combinator on the receiver.
Output medium width
Return the document produced by f
when it is passed the column at which
rendering is currently placed.

method. Called nil
in the paper.

string repl
if the break is omitted by a group.

(Since version 1.2.1) Use PrettyPrinter.any instead.
The interface of a pretty printer using combinators from Swierstra and Chitil (Linear, bounded, functional pretty-printing, Journal of Functional Programming, 19 (1), 2009) and Leijen's PPrint library. The latter is a version of Wadler's library which was inspired by an earlier library by Hughes.
