Cpp (C preprocessor) tricks

Maybe we can bring them back in the form of something that approximates C++ lambdas. My first impression of lambdas is they shared some of the functionality of statement functions. As I tried to point out above they also can be used in some cases in the place of cpp logic and as you point out have the advantage of offering a greater possiblility of inlining. The biggest advantages I see of lambdas is they can be defined anywhere in the code and like block constructs can contain explicit typing. So maybe a lambda block construct would give us the advantages of statement functions without what I see is their biggest problem which is a potential for confusion with arrays and in general readability.
