see how to do this without loop myself over the string array. 
Is there
a native function or should I write it myself?

Try this:

        import std.array : appender;
        import std.algorithm : joiner, copy;

        string[] arr = ["ab", "cd", "efg"];
        auto app = appender!string();
        arr.joiner.copy(app);
        assert(app.data == "abcdefg");

FYI, that's probably scary expensive in terms of 
encoding/decoding.

Using the "free" std.range.put should take care of everything, 
natively.
