An extract from java.util.Formatter docs:

// Explicit argument indices may be used to re-order output.
formatter.format("%4$2s %3$2s %2$2s %1$2s", "a", "b", "c", "d")
// -> " d  c  b  a"

How do I achieve this with std.format? The ddocs only say that "variadic arguments are consumed in order". Any way to change that order?

I think you can't (and I haven't had the need to do it).

It's somtimes needed with I18N code.

With the D Tango library you can put:
Stdout.format("{3} {2} {1} {0}", "a", "b", "c", "d");
