Aryadev Chavali b29855047b Implement $ operator, second class version of the applicative operator ...

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.
