I got this to work with:

        std.file.write("test.csv", "0,1,abc\n2,3,def");
        scope(exit) std.file.remove("test.csv");

        static struct Rec { int a, b; char[] c; }

        auto file = File("test.csv", "r");
        foreach (s; csvReader!Rec(file.byLine().joiner("\n")))
        {
                writeln("struct -> ", s);
        }
}
```

I am not sure about using `file.byLine()` here, because 
`byLine` reuses its buffer, but this is working correctly (for 
some reason, anyone can comment?) as far as I tested.

Btw, joiner is a lazy algorithm. In other words, it doesn't join 
the whole file when it is called but only when needed. This 
reduces the memory requirements as you won't need the whole file 
in memory at once.
