Object.prototype.propertyIsEnumerable does not consider properties in
the prototype chain. In effect, propertyIsEnumerable is a test to see
if an object has *own* property that is also enumerable.
And just when I was thinking I was finally beginning to understand
this language :(. I wonder what other gotchas I'm still missing?
See

filed by David Flanagan on 2000-10-17. My comment 11 is from
2000-12-01. This was an ES3 design-by-committee botch, never
corrected. The spec originated the feature, no browser implemented
anything like it first. SpiderMonkey tried doing it right as the bug
shows, but no good deed goes unpunished.
