Description Boris Zbarsky 2014-03-12 21:20:42 UTC
Consider an interface with a named creator and [OverrideBuiltins] (in fact, the only interface with a named creator in the platform has that extended attribute).

When a set happens for a currently-nonexistent, per current spec [[GetOwnProperty]] will return undefined.  Then the ES impl will go up the proto chain looking for a setter, and if found call it.

That doesn't seem correct; we actually want to call the named creator in this case.

We should probably just override [[Put]] when we have a named creator.  And maybe transition all this stuff to the ES6 MOP in the process...
