The tuple-lenses package

[Tags: bsd3, library]

This package provides some stock lenses for swizzling tuple elements. For instance:

> (1,2,3)^._13
 (1, 3)

The package provide all lenses that are in increasing order, for FieldN classes 1-9. If you want to swap the order or permute the elements, you need to make your own.

Custom combos are provided by a Template Haskell function.

> ('a','b','c','d') ^. $(tl [4,1,2,3])
 ('d','a','b','c')
