€ - Each
Tags: hyper , array
The resulting link's arity is the same as the consumed link's arity. Note that the arity refers to that of the resulting link, not the number of links this quick consumes.
Map the link over its left argument, automatically casting numbers to a range.
If given a nilad, this quick returns a monad which just calls the nilad once per element and produces a list of the results. If given a dyad, the resulting link is also a dyad, and it will loop over the left argument and apply with the same right argument each time.
