[DGD] "mixed" question

[Jason Cone]

Greetings.

In looking at some code that I wrote some time ago, I've become curious
about something.  Specifically, what is the difference between (mixed),
(mixed *), (mixed **), etc.?  Because you can represent a (mixed) value
with a (mixed **) value and vice versa, there doesn't seem to be any
difference at all.  I'm sure, however, that there are some
efficiency/overhead issues to consider.  What are they?  If programmatic
differences do exist, feel free to clue me in on those as well.
