This variable is new in release 6.0. Performance testing has indicated
that the overhead associated with pretty printing can be high. In
order to better control this cost, no Allegro CL code sets the value
of *print-pretty*. Instead, Allegro CL code binds
it where necessary to the value of this variable, and this variable is
only set in two places: initially to nil and
in the :pprint module to t.
See Speed and pretty printing in release-notes.htm for more information on the pretty-printing issue.
The documentation is described in introduction.htm and the index is in index.htm.
