This allows the lib fixed point to be extended with
myLib = lib.extend (self: super: {
foo = "foo";
})
With this it's possible to have the new modified lib attrset available to all
modules when using evalModules
myLib.evalModules {
modules = [ ({ lib, ... }: {
options.bar = lib.mkOption {
default = lib.foo;
};
}) ];
}
=> { config = { bar = "foo"; ... }; options = ...; }
