clone is used to make a new vector. V{ } creates a vector at
parsetime, and when the code is run, a reference to that vector is
pushed onto the stack. If this vector is manipulated, it will
manipulate the original copy. Sometimes this is what you want to do,
but if you want a *new* empty vector, you have to clone it. Another
way to accomplish this is 0 <vector> . There's no particular reason to
use one or the other.
