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
}
-------------------------------------
