`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}'.
