But it you need to have a modified version of this this, you create its

This confuses me very.
Do you mean, there is no Copy-On-Write semantic in D?
IMO, D-Compiler should make decision about whether to allocate a new

No, arrays have reference semantics (unlike std::string in C++) and thus
changing data an array points to will have effect on all other arrays that
share same data.
