It seems it is already there, or did you need a non-vanilla Lua to run

I mean a ?. operator...
If you set the nil metatable to return nil (thanks for the bug report in my example) then all kinds of helpful errors dissapear. I played with this for a bit and productivity tankened. As is, Lua doesn't have a more terse/clear way than:
if a.b and a.b.c.d and a.b.c.d.e then...
In this example, the op is looking for:
if a.b?c.d?e then
...
Where a==nil would error.
This is something that I would think would make code clearer.
