Thank you very much, it works like a charm.
I wrote a small function to log whatever object I pass to it:

void log(T)(T obj)
{
        static if (is(T == struct) || is(T == class))
        {
                writef("{");
                foreach(i,_;obj.tupleof)
                        writefln("%s : %s,", obj.tupleof[i].stringof[4..$], 
obj.tupleof[i]);
                writefln("}");
        }
        else
        {
                writefln(obj);
        }
}

Are there better solutions than this or does it perhaps have any flaws?

One note is that you should probably pass the object by reference:

void log(T)(ref T obj) { ... }        // D1
void log(T)(ref const(T) obj) { ... } // D2
