I think the docs imply strongly that the result sequence will be
the same length as the first sequence:

Complexity:

  Linear. Exactly ... size<s1>::value applications of op / op2 and
  in::operation

...although the semantics are stated in terms of pair_view, which is
never defined in the docs (ahem!)

As for the exact type of the result, well, MPL transformation
algorithms never tell you that, regardless of the inputs.
