Fantasy-land: Apply strictness

[ulfryk]

Apply docs state:

---

A value which has an Apply must provide an ap method. The ap
method takes one argument:

a.ap(b)

1. b must be an Apply of a function,

---

shouldn't there be requirement that _b must be same Apply as a_ ?

[gabejohnson]

There should also be a fourth clause stating:

ap must return a value in the same Apply as a and b

Or something to that effect.
