Yah, I was thinking of a unified and backwards-compatible sig:
string toString(void delegate(const(char)[]) sink = null,
string fmt = null);
With null inputs toString works like today. When provided a sink, it
outputs to the sink and returns null.

Have you given any more thought to the issue of user-defined types that
want to define a more elaborate toString() signature than the trivial
one?
It seems that with your recent change to output ranges, both
BigInt-style toString(),
void toString(void delegate(const(char)[]) sink, string fmt);
and Complex-style toString(),
void toString(Writer)(ref Writer writer, string fmt)
if (isOutputRange!(Writer,string))
could be supported without making special cases for each.
