Yes, "p=pack". "s" seemed to be used elsewhere in <expression> for
various operators, and I didn't want to take another single-letter
code. 'D' was just convenience, and again, I'm getting nervous about
single-character codes, so I decided to turn 'D' into a prefix that we
can use for more types later on.
