$input is the method invocant (hence the “:”) constrained to a defined string object. $limit is the number of words (chunks separated by whitespace) you may want from $input - -> constrains the return type to an object that consumes the role of Positional > HOW IN THE WORLD did they convert `$limit = Inf` into an > array index!?!?
