Yeah. If you want to use an array for a stack, it really needs to be wrapped 
in a struct or class like you'd do in C++. Expanding it when the size of the 
array needs to increase to accomodate items pushed onto the stack is certainly 
much easier in D, but trying to use the array as a stack directly is definitely 
going to cause issues as you show in the article.
