New submission from David W. Lambert <lambertdw at corning.com>:
(After fixing the link to http://docs.python.org/3.0 at http://www.python.org/doc/ (and likewise the http://docs.python.org/whatsnew/3.0.html link.)...
The comment that __getattribute__ is "Called unconditionally to
implement attribute accesses for instances of the class" gave me hope
that some combination of "meta" "super" and "sub" might let me access
__getattribute__ for expression eval('obj + another_object') despite the
special notes. I realize now the truth is that
"__getattribute__ is NEVER accessible in pure python code when the code
uses the syntax of a unary or binary operator such as a+b, ~a, len(a)."
See most of the functions in this manual section.
Also name hash, which doesn't find much explicit use but could well be
the most used python functionality. Find a smooth way to replace my
NEVER since code can obviously access __getattribute__ from the special
Thank you, and great work!
