QOTW:  "There's no RightAnswer(tm), just our best guess as to what is
the most
useful behavior for the most number of people." - Raymond Hettinger
   http://groups.google.com/group/comp.lang.python/msg/e7f78ef27811781b


   First beta version of Python 2.7 is available:
       http://groups.google.com.ar/group/comp.lang.python/t/d036954e11a264dd/

   Why still a 2.7 release, when 3.1 is already out?
       http://groups.google.com.ar/group/comp.lang.python/t/f8a5028affe772ed/

   Deciding when to pass around a parameter, and when to keep it as an
   instance attribute:
       http://groups.google.com.ar/group/comp.lang.python/t/6f51302327b58aac/

   A class is more than just a container for functions and attributes:
       http://groups.google.com.ar/group/comp.lang.python/t/5525bd981dd9ece6/

   Lie Ryan tries to explain the various escaping levels of a regular
   expression string:
       http://groups.google.com.ar/group/comp.lang.python/t/3a27b819307c0cb6/

   Peter Otten shows how to make string.Template resolve dotted.names
from
   nested dictionaries:
       http://groups.google.com.ar/group/comp.lang.python/t/d482f74d16fcbbb2/

   Simple string operations, regular expressions, and a full blown
parser:
   the right tools for different jobs
       http://groups.google.com.ar/group/comp.lang.python/t/888b3fe934e2c5e2/

   The list comprehension loop variable, nested scopes, and common
sense
   applied to programming languages:
       http://groups.google.com.ar/group/comp.lang.python/t/2b64b9a9069a324f/

   Performance of list vs. set equality operations -- later:
encapsulation,
   the Open/Closed principle, and why overriding __special__ methods
may
   not affect certain built-in type operations:
       http://groups.google.com.ar/group/comp.lang.python/t/818d143c7e9550bc/

   __del__ methods are not the same as C++ destructors; they might not
even
   be called:
       http://groups.google.com.ar/group/comp.lang.python/t/6c875525954df888/

   Abstract Base Classes affect the way issubclass() works -- it's not
   based only on the chain of MRO anymore:
       http://groups.google.com.ar/group/comp.lang.python/t/bd97c8e475e4da67/

   wxPython and a bad example of 'property' usage:
       http://groups.google.com.ar/group/comp.lang.python/t/d88a38bbbb7b5dca/

   Keeping client expectations realistic and avoiding scope creep:
