A more natural way is pragma(msg), which you can use in main in this case:

string test(string s)
{
     string tmp = s;
     tmp = tmp[4..$];
     return tmp;
}

enum foo =
`1234
5678
`;

void main()
{
     enum bar = test(foo);
     pragma(msg, bar);
}

Yes, looks pretty weird. :) I remember issues related to Unicode 
characters, which may be fixed by now, but the [4..10] part is news to me.
