Hi Mark,
you didn't waste my time.

That is an error, IMO. There are expressions that yield the (Unset) value.
The only difference between this value and any other value is, that the
interpreter, when an expression yields the (Unset) value, doesn't print
== unset
at the console. Nevertheless, you can easily make sure, that a block like
[print 1]
really yields the (Unset) value when evaluated.
Cheers
