One possibility to take the magic away from [[Put]] would be to revisit 
something that appeared while talking about "shared part" discussion on 
non-writable inherited properties. That is, to include fourth attribute, 
shadowable, with default on true; which when false, would mean the 
[[DefineOwnProperty]] trap should be called on containing object, not on 
this.
