So the member cannot be named as 'length':struct Array (T) { size_t length_; T* ptr; } Anyway... :) Ali
Reminds me of how Delphi (aka Pascal) strings are work. Thanks everyone this answers some of my questions. Now what about when the return type of a function is a string? Is D returning the pointer to the string structure or is it returning the structure?
