What is the result type of transform if the algorithm is given two sequences of different sizes?

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

That was the intented semantics, but it appears that tests don't cover this case, and things don't quite work as they supposed to. I'll take a look at it.

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!)

Yes, it's a known issue. -- Aleksey Gurtovoy MetaCommunications Engineering
