Yes, I believe that this is a problem in D, and because when you 
create a multidimensional array mutable strings having real 
troubles with .deepDup. I think that will solve the problem of a 
new string data type is a built-in D, and because writing .dup, 
to create a mutated string, - it's really funny! This is problem!
