Re: [Vala] Vala : Suggestion for improvement : String Class wrapper for strings in Vala

You will notice that in the second case (the naive straightforward
formulation) the data is duplicated (passed by value in the
assignment) whereas in the first case (which uses a class wrapper) the
object a is assigned to b by reference (not by value, i.e. the data is
not duplicated)

'string' is a kind of primitive in Vala, it's designed to be passed by
value. Just like int, double, etc. in C. If you want not to duplicate a
string, use 'unowned' keyword, like:

    string a = "hello";
    unowned string b = a;
