Those works because you are actually assigning to root.

That is not assigning anything to the root... that is obtaining the
'sub1' table from root, then assigning the 'foo' element to the value
'bar'.

One potential fix is to, in the __newindex call, attach a metatable to
each new table value of root... if you know that the assigned tables
will not have any metatable, then all is simple... otherwise you'll
have to be sure to properly chain.
