If you want to give format specifier for elements explicitly, you should use
compound format specifier (It is %( and %).)
writefln("[%(%12d, %)]", [1, 10, 5]);
writefln("[%(%12s, %)]", ["red", "yellow", "ya"]);
But, this code output:
[ 1, 10, 5]
["red", "yellow", "ya"]
Because, string elements and character elements are treated specially. They are
quoted, and other specifications are ignored.

But, I agree it is debatable thing.
