char[][] to std::vector<std::string> - DIP or dmd-issue?

[Dennis Ritchie via Digitalmars-d-learn]

Hello, everyone!

I like to work with arrays of strings like `string[] strArray`, 
but unfortunately, they are immutable.

I do not like to work with arrays of strings such as `char[][] 
strArray`, because it is necessary to apply the method .dup each 
substring to make them work :)

I understand that the type of `string[]` to D is a simple data 
type than `char[][]`, but it seems to me that the problem is 
solved in C++:
std::vector<std::string> stdArray;

I wish to propose the creation of new types of data D: str, wstr, 
dstr, which will be the analogs of C++ `std::vector<std::string>`.

I do not know whether it is possible to create in the D, but I 
want to know where I write a sentence?
Can I file a dmd-issue, or should I create a DIP, because it is 
too big improvement?
