Should we curry / combine arguments?

We could combine arguments to the initial wrap and the final task making call

``` js
function add(a, b) { return a + b }
const makeAdd2 = voTask(add, 2)
const add2to5 = makeAdd2(5)
add2to5.fork(...) // result is 7
```

Start by reviewing the existing voTask API and the example in this issue. Determine whether initial arguments should be accepted by voTask and whether the returned function should accept the remaining arguments before producing a task. Done means the proposed add example works and the intended argument-combining behavior is covered by tests.
