           Summary: Numeric setter on prototype doesn't get called.
    Classification: Unclassified
           Product: WebKit

          Hardware: Unspecified

            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

var y = {set 2(x) { alert(x) }}
y[2] = 5;
var z = {__proto__: {set 3(x) { alert(x) }}};
z[3] = 7;

Chrome and Firefox both alerts 5 and 7.
Safari only alerts 5.

If you replace '3' with 'foo', Safari also alerts 7 and 7.
