I think I can handle it. :)

The problem is that arrayarray.pxd is only used when the exporter is typed.
This means that you can't do this:
def func(int[:] arr): pass
func(array.array('i', [1,2,3]))
but it will work if func() is defined like this:
def func(array.array arr):
cdef int[:] view = arr
I admit that the wording in the release notes is wrong, I wrote it because
I initially thought that you had to do this:
def func(array.array[int] arr):
cdef int[:] view = arr
But no, you don't have to use the buffer interface, you just have to type
the variable. I'll update the release notes.
Works better in Py3, obviously.
