* Another experimental feature: a way to truly override attributes in
a rec. This will be very useful to allow end-user customisation of all-packages.nix, for instance globally overriding GCC or some other dependency. The // operator doesn't cut it: you could replace the "gcc" attribute, but all other attributes would continue to reference the original value due to the substitution semantics of rec. The syntax is a bit hacky but this is to allow backwards compatibility.
