JS Range object should support ==

IMO document.createRange() == document.createRange() should return true.

Moreover:
var range1 = document.createRange();
range1.setStart(textNode, 0);
range1.setEnd(textNode, 1);
var range2 = document.createRange();
range2.setStart(textNode, 0);
range2.setEnd(textNode, 1);

range1 == range2 should return true
range1 === range2 should return false

Likewise:
var range1 = document.createRange()
var range2 = range1.cloneRange();

range1 == range2
should return true

FF does not support this behavior, but it makes sense from a user perspective.  Maybe it doesn't make sense from a JS language perspective?

Of course then, what do we do if someone sets custom JS attributes on the Range.

Hum.. ECMAScript seems to disagree with me:

So sad.
