Hi Ali – I take this chance to personally thank you sincerely for your book which provides much-needed hand-holding in my baby D-steps. I did read that chapter already and IMO you have given clear instructions as to when to use const and when immutable. My question was however to the root of the issue, as to *why* the compiler cannot consider mutable as immutable just like in C/C++ any non-const can be taken as const. It would seem that the answer is one related to optimization. Obviously, labeling an argument as immutable can be done only if we are sure that we will have to process only immutable input, thereby paving the opportunity for the compiler to optimize some memory access or allocation or such – I'm not much clear beyond that but that's enough for me now... -- Shriramana Sharma, Penguin #395953
