If you want to stop automatic element quoting, you can use "%-(".

void main()
{
    auto ror = ["one", "two", "three"];
    writefln("%-(%s%| %)", [1, 2, 3]); // 1 2 3
    writefln("%-(%s%| %)", "abc");     // a b c
    writefln("%-(%s%|, %)", ror);      // one, two, three
}

It's documented in: http://dlang.org/phobos/std_format

> Inside a compound format specifier, strings and characters are escaped
