Comment #2 on issue 1837 by [email protected]: Defining properties in
Object.prototype returns invalid (boxed) values
http://code.google.com/p/v8/issues/detail?id=1837
For the record, the boxed value is the correct result. The 'this' value of
a non-strict user-defined function is always an object, not a primitive
value.
if you change the code to:
Object.defineProperty(Object.prototype, "toArray", {value: function() {
"use strict";
return Array.isArray(this) ? this : [this];
}});
then the primitive value will not be boxed.
The bug in issue 1973 is that the getter doesn't properly box the 'this'
value.
