* In an nested with' where the inner with is a variable (

* Change the semantics of "with" so that inner "withs" take
...
precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
This has a simpler implementation and seems more natural. There
doesn't seem to be any code in Nixpkgs or NixOS that relies on the
old behaviour.

* Make `derivation' lazy again for performance. It also turns out

that there are some places in Nixpkgs (php_configurable /
