I'm replying to a stream of earlier messages.
Regarding toString etc., I hope to get some work done on that this weekend.

Eventually, whatever is chosen will require some changes to
std.format, but I'd just like to get a reasonable first cut for the
initial release.
That's fine; we need to look again at std.format anyway.
Since Complex needs a toString() function as well, I am wondering: Has
the above been decided on as the standard for to-string conversion?
I'm asking because the newest part of std.format seems to be
formattedWrite(), which writes to an output range. Thus, an alternative
would be
void toString(OutputRange writer, string format);
IMO this seems more flexible, since the sink delegate solution is easily
implemented as a trivial output range. You can't necessarily do it the
other way around (for instance, it requires quite a bit of typing if you
just want toString to fill a buffer array).
Whatever it is, there really should be a standard signature, so that
library and user types may work seamlessly with the writef*(), format()
and to!string() functions.
