Isn't that just a matter of replacing each of the segments with their

writeln-formatting into a buffer (well, any output range, really) -- I'm
pretty sure it doesn't allocate, at least for the simplest cases like
converting an integer. So you should be able to do something like this:
auto data = [ 1, 2, 3, 4, 5 ];
char[] buf = ...;
formattedWrite(buf, "[%(%d, %)]", data);
Aha, interesting. I didn't know formattedWrite could format an
array/range directly like that.
The more complex example works by defining "toString" which takes an
output range (delegate). But what if I need to format a third party type
that I cannot add methods to? UFCS does not seem to work.
