I didn't suggest we turned augmented assignment 'on' in beta phase, and
removed it if it turned out too confusing. I was thinking more along the
lines of the recent 'usability study' of parallel loops. Urging people to
install the patch just to see how it works, and if it works how they

The point is we can argue all year long about how <this> will be confusing
because of <that>, and <this> too confusing for users of <that>, and this
too confusing if you come from <that> language. We probably all are right,
too ! But in the end we have to decide whether the new functionality is
worth the extra confusion. And part of that is determining how confusing the
new syntax and semantics really are, for those used to Python and those new
to Python.
