It could be done easily by add few lines of code to std.format.formatValue.

Adding something like this:

else static if (__traits(compiles, val[]) && isInputRange!(typeof(val[])))
    {
        auto refVal = val[];
        formatRange(w, refVal, f);
}

to

void formatValue(Writer, T, Char)(Writer w, auto ref T val, ref FormatSpec!Char
f)
if ((is(T == struct) || is(T == union)) && (hasToString!(T, Char) ||
!is(BuiltinTypeOf!T)) && !is(T == enum))
