Description
Each
class Each s t a b | s -> a, t -> b, s b -> t, t a -> s where Source #
Extract each element of a (potentially monomorphic) container.
Notably, when applied to a tuple, this generalizes both to arbitrary homogeneous tuples.
>>>(1,2,3) & each *~ 10(10,20,30)
It can also be used on monomorphic containers like Text or ByteString.
>>>over each Char.toUpper ("hello"^.Text.packed)"HELLO"
>>>("hello","world") & each.each %~ Char.toUpper("HELLO","WORLD")
