The pep has been through several rounds of public comment on
comp.lang.python.  As a result, the proposal has evolved away from
several methods called iter_backwards() and into a simple builtin
function called reversed().  Other simplifications emerged as well.  The
improved pep is at:

    www.python.org/sf/pep-0322.html

Thanks to many posts by Alex, the only issue of significance is avoiding
having a new builtin. My strong feeling is that the essential simplicity
and utility of the function would be lost if it got tucked away in some
other namespace.  The flipside is our common desire to keep the builtin
namespace as compact as possible.

So, I would like to solicit your thoughts and judgments on whether the
PEP merits a new builtin.

The proposal and remaining issue are both so simply stated that it was
difficult to keep the newsgroup discussion focused.  The posts
immediately veered towards developing exotic ways to attach the function
to other namespaces.  Instead of repeating that discussion, hopefully we
can just decide whether to accept the pep.

Thank you,

Raymond Hettinger
