I'm sorry, Bastian, but can I ask you what you're trying to achieve
with these lines? Actually, I've never seen more than one SetDelayed
in an expression. When I try to test this definition as follows, I get
a "SetDelayed::shape"  error,

{x, y, z, w} :=  Let[{a = 1, b = a + 1, c = b + 1, d = a + b + c}=
, {a,
b, c, d}]

Other than this, thanks to you and Daniel for these nice recursive
versions of With.
Igor
