Object.merge, maybe -- but definitely do not want this muddled into
assign/define or put/define or whatever those shallow-only names should be.

1. Why implicitly bind any function value?
2. Ditto for get and set accessor functions?
3. Why Object.defineProperty if !(key in target)? Why not just always
assign, since this is Object.put and not Object.define?
