[Python-Dev] More Zen

[Raymond Hettinger]

Iterators unified access to containers -- lets find more of those.
Substitutability simplifies development 
    so shelves have a full dictionary interface
    but tuples won't sprout a count method
    because lists differ in intent.
Deprecation comes at a price but cruft has a cost of its own.
Holistic refactoring beats piecemeal optimization.
Comment generously, the best modules are an education to read.
Be kind on the Usenet some posters are only eleven.
