Reduce selected dimensions.
Alternatively you may reorder dimensions with `backpermute`

and fold once along a multiple dimensions.

- data T sh0 sh1 a
- type Linear sh0 sh1 = T (Shape sh0) (Shape sh1)
- apply :: (C array, C sh0, C sh1, C a) => T sh0 sh1 a -> array sh0 a -> array sh1 a
- passAny :: Linear sh sh a
- pass :: Linear sh0 sh1 a -> Linear (sh0 :. i) (sh1 :. i) a
- fold :: C a => (Exp a -> Exp a -> Exp a) -> Linear sh0 sh1 a -> Linear (sh0 :. Int) sh1 a
- ($:.) :: (Process proc0, Process proc1) => proc0 -> (proc0 -> proc1) -> proc1

# Documentation

($:.) :: (Process proc0, Process proc1) => proc0 -> (proc0 -> proc1) -> proc1Source

Use this for combining several dimension manipulators. E.g.

apply (passAny $:. pick 3 $:. pass $:. replicate 10) array

The constraint `(Process proc0, Process proc1)`

is a bit weak.
We like to enforce that the type constructor like `Slice.T`

is the same in `proc0`

and `proc1`

, and only the parameters differ.
Currently this coherence is achieved,
because we only provide functions of type `proc0 -> proc1`

with this condition.
