.~ ) :: ASetter s t a b -> b -> s -> tlens Control.Lens.Operators Replace the target of a Lens or all of the targets of a Setter or Traversal with a constant value. This is an infix version of set, provided for consistency with (.=).

>>> (a,b,c,d) & _4 .~ e (a,b,c,e)

>>> (42,"world") & _1 .~ "hello" ("hello","world")

.~ ) :: ASetter s t a b -> b -> s -> tmicrolens Lens.Micro (.~) assigns a value to the target. It's the same thing as using (%~) with const:

l .~ x = l %~ const x

See set if you want a non-operator synonym. Here it is used to change 2 fields of a 3-tuple:>>> (0,0,0) & _1 .~ 1 & _3 .~ 3 (1,0,3)
