Sean, David, Goran, Tryvge and others: thanks for your insights and
your reading recommendations.

I have since read that about a year ago, the Program By Design /
Racket group of academics(*) posted an online draft of their
Java-based sequel to 'How to Design Programs'. As far as I can tell,
the new book has a couple of working titles : 'How to Design Classes'
and 'How to Design Components'.

I haven't read it, but the premise of the book seems to tie in with
Frank Shearer's comment about objects being higher order functions
that close over variables. The preface, which includes a one-line
quote from Alan Kay, may prove interesting to the readers of this
thread.
