This code doesn't work well:
--------------------------------------
import std.stdio;

void foo(ref string[] data)
{
    foreach (ref e; data)
    {
        e = e ~ "!";
    }
}
string[] bar(string[] data)
{
    foo(data);
    return data;
}
void main()
{
    enum data = ["a", "bcde", "abcde"];
    enum resCt = bar(data);
    auto resRt = bar(data);
    writeln(resCt); // NG: ["a", "bcde", "abcde"]
    writeln(resRt); // OK: ["a!", "bcde!", "abcde!"]
    assert(resCt == resRt); // NG
}
-------------------------------------
