Well, one of the reasons for typesetting your own technical books is
the accuracy of code samples.

The Ruby book we're writing currently has over 1,200 code samples in
the text. Traditionally, we'd have supplied the publisher with each on 
a separate sheet of paper, with a reference number tying it back to
the place it belongs in the source. The code would then be manually
entered, and we'd have to scan each, again manually, for any errors.

However, typeset the book ourselves, and we have other options. In our 
case, the code sits inline in the source of the book. Every time we
format the book, the code gets executed. In many cases, the output is
then inserted back in to the book. During the production of the book,
these code samples have found bugs in Ruby, and fixes to Ruby have
found bugs in the code samples.

The expected result for us is a more accurate book.

Ruby actually has a method 'class' in object:

   p 1.class   # => Fixnum

In terms of how it works: In this case, the use of 'class' as a method
name is unambiguous, so it says "go for it". In fact, the parser
actually makes a special case of just this, casting the reserved word
into an ID for the occasion.
