Plurality ​

A function or program can easily be called on a list of values using plurality syntax. This is done by adding a ! symbol at the end of the function name in a call.

["hello", "world"] | len! #=> [5, 5]
"123" | into::int!        #=> [1, 2, 3]

["hello", "world"] | len! #=> [5, 5]
"123" | into::int!        #=> [1, 2, 3]
