You will find that only foo is set set to a block, whereas bar and baz
are initialized to the value none. This is unlike using
set [foo bar baz[] 3 ;- (i.e. some non-series value
where all words will be initialized to the same value.

Note that, unlike in Greg's example, here all three words will be set to
one and the same block. I.e. any modifications made to the block baz
will also affect the blocks foo and bar, because they are one and the
same block.
