printing lists

[Erik Naggum]

another question about near-trivial Common Lisp requirements.

ANSI X3.226 section 22.1.3.5 Printing Lists and Conses clearly states how a
list should be printed. however, is there room for printed forms that
exploit the readtable? e.g., '(quote foo) => 'foo, '(function foo) =>
#'foo, '`(foo ,bar) => `(foo ,bar). if so, how would it be requested?

There's no standard way to request this. Some implementations do this
automatically, although they must provide a way to turn it off in order to
get standard-conforming output (it's generally controlled by some
*PRINT-xxx* variable and a corresponding :xxx argument to WRITE).
