writefln("%(%s-%)", ["a", "b", "c"]) doesn't print the intended a-b-c but surrounds each string with double quotes - "a"-"b"-"c", which I find inconsistent with the fact that writefln("%s", "a string") prints the string without any quotes.
How do I get the desired behaviour using just the format string?

writefln("%-(%s-%)", ["a", "b", "c"])

Thanks! The Ali's book is indeed superb, covering even such minor details.

What I find surprising is that "%-(ch%)" without %s inside also works, although ch is prepended to each string and not a separator (which makes sense, but still).  This does not seem to be mentioned in the documentation, neither in Ali's book.  Is this a bug?
