How can I make an existing object read-only?

Will your book also be influenced by Design Patterns in Dynamic
Languages e.g. Common Lisp? Peter Norvig argues that 16 GoF Patterns
are simply workarounds of C++ like language shortcomings. It would be
very interesting to see such a discussion for Python. Also, Norvig's
slides are somewhat too terse for me (as well as Lisp macros etc.).
It's a pity that most of the pattern books are based on the GoF book
only.

I recommend The Design Patterns Smalltalk Companion, an excellent book.
And yes, I have the same observation on some of _my_ too-terse slides
(at www.strakt.com): some classic patterns are workarounds for static
typing (and, also, for non-firstclassness of some constructs, to a
lesser extent).

Outside of the GoF's book, there's actually a wealth of pattern books.
Fowler's "Analysis Patterns" and "Refactoring", all the PLoP books,
Schmidt's work (http://www.cs.wustl.edu/~schmidt/patterns-ace.html),
etc, etc...

Hello Alex,

Yep -- I've been writing about DPs with/for Python for years now (that's
the invariable background to almost all of my conference talks &c, check
most of them out at www.strakt.com), and one day (once I'm done doing
2nd editions of cookbooks and nutshells;-) I hope to write a book about
that (plus materials on agile programming practices, again with Python
as the explanatory language).
