* Allow a default value in attribute selection by writing
x.y.z or default
(as originally proposed in
https://mail.cs.uu.nl/pipermail/nix-dev/2009-September/002989.html).
For instance, an expression like
stdenv.lib.attrByPath ["features" "ckSched"] false args
can now be written as
args.features.ckSched or false
