We now care (a little bit) about the "configurable" and "writable" property attributes. Property attributes are stored together with the property name in the Shape object. Forward transitions are not attribute-savvy and will cause poor Shape reuse in the case of multiple same-name properties with different attributes. Oh, and this patch also adds Object.getOwnPropertyDescriptor() :^)
