* Added plain lambdas, e.g., `let { id = x: x; const = x: y: x; }'.
...
`bla:' is now no longer parsed as a URL.
* Re-enabled support for the `args' attribute in derivations to
specify command line arguments to the builder, e.g.,
...
builder = /usr/bin/python;
args = ["-c" ./builder.py];
...

* Added syntactic sugar to the construction of attribute sets to
...
`inherit' variables from the surrounding lexical scope.
E.g.,
{stdenv, libfoo}: derivation {
builder = ./bla;
inherit stdenv libfoo;
xyzzy = 1;
}
is equivalent to
{stdenv, libfoo}: derivation {
builder = ./bla;
stdenv = stdenv;
libfoo = libfoo;
xyzzy = 1;
}
Note that for mutually recursive attribute set definitions (`rec
{...}'), this also works, that is, `rec {inherit x;}' is equivalent
to `let {fresh = x; body = rec {x = fresh;};}', *not*
`rec {x = x}'.
