Nice quote from the cover of R2RS

[Mark H Weaver]

At a friend's house I found a printed copy of R2RS, aka MIT AI Memo
848, dated August 1985.  I include the cover text below.  Readers of
Tolkien will appreciate the quote.  I wonder if it might be included
in the Guile manual for fun.

                                             The Revised

                                             An UnCommon
                                                    Lisp

Data and procedures and the values they amass,
Higher-order functions to combine and mix and match,
Objects with their local state, the messages they pass,
A property, a package, the control point for a catch--
In the Lambda Order they are all first-class.
One Thing to name them all, One Thing to define them,
One Thing to place them in environments and bind them,
In the Lambda order they are all first-class.
