[Nix-dev] confused using the <obj> ? <string> operator with non literal operators

Yes, that is a good explanation. I think I also found the dot operator
a bit surprising back in time, but doesn't seem it bothered me enough
to ask in the list :)

I just read what it does in the Nix manual:
http://nixos.org/nix/manual/#table-operators

Neither . nor ? say anything about how the rhs is evaluated. Though
the manual does clarify what you just explained here
http://nixos.org/nix/manual/#idm46912467652128.

I am not sure wether it makes sense to reiterate that in the operators
section or if my confusion is just a fluke :)
