Didn't see that as a `cycle` but it makes sense. Does Julia have a `cycle` equivlant?

- Like most languages Julia does not, by default, allow operations on
  unequal length vectors by cycling the shorter one. Julia will throw errors
  when the lengths of inputs do not match, unlike R in which
  ``c(1,2,3,4) + c(1,2)`` will evaluate to ``c(2,4,4,6)``.
