Is it possible to have this output [null,"1"] in stead of Error: std.format
formatArg?

interface I{}
class C:I{
int index;
char[] toString(){ return toString(index) }
}

I[2] two_i;
I[1] = new C();
writefln(two_i);



Would be handy for debugging ;)

s/interface I{}/interface I{ char[] toString(); }/
s/writefln(two_i)/writefln("%s",two_i)/

?

or see bug 535

Don't think this is exactly what you are looking for, but have you tried  
writeln?  writefln requires the first argument to be a string, it didn't  
used to, but it was determined that the resulting behavior when you want  
to just print a string is too confusing.
