The `$` operator takes a sequence of FORMS and returns a unary function which applies the input through that sequence via the `->>` operator. For example, consider the predicate "not null". `null` is built into Common Lisp but "not null" requires writing a function (lambda (x) (not (null x))). Now, using this operator, you can write ($ not null) which returns the same lambda as above while being more concise.
