I try to describe my question in another way.

When call luaH_newkey(https://github.com/lua/lua/blob/master/ltable.c#L636), it first call 'mainpositionTV' to find the 'mp'。

If the 'isempty(gval(mp)) == true  && gnext(mp) != 0', it don't correct the chain.

What are the disadvantages if it correct the chain at this case.

Maybe for performance or other reasons?
