The set-word isn't needed.

The use of CLEAR modifies the series to which FOO refers, so you
don't need to set the result back into FOO. If you want to do
the removal and then immediately use the truncated value, then
prepending the HEAD will yield that value without the need for
another reference to (or setting of) FOO, as in
>> foo: "0123456"
>> head clear skip tail foo -2
