IIUC, its ctor just do the job, not?

The problem is I don't know the arity or parameter types of the function
being called. I just have a source of data (which can be simplified to TYPE
data = data_source<TYPE>().pop();) and arbitrary functions being passed in.

One alternative is to code-generate template specializations for a bunch of
arity and use the constructor like you suggested. But I feel the "arity code
generation" thing has been done so many times and so much better in boost
that I should be able to use a transform or invoke function to take
advantage of that. That's why I started trying to use fusion.
