The dashes aside, this is exactly what I usually did back when I
used to write business letters and technical documents. Whenever a
series got too long or complex and I wanted to be certain sure that
everything was perfectly clear, I would go to a bulleted list. Or,
If I were going to refer back to any of the items, instead of
bullets I would label the items a, b, c... or number them.
Some people do object to bulleted lists but IMO they do wonders for
clarity. Of course I wasn't trying to write literature, I was just
trying to be clear.
