This is critically important -- no one looks at the language spec to figure
out how something works -- they try it, and if it works assume it will
continue to work.

if dict order is preserved in cPython , people WILL count on it!

And similarly, having order preserved only until a delete is going to cause
bugs in people's code that are less than careful :-( -- and that's most of
