An implementation of the

[Push programming language](http://faculty.hampshire.edu/lspector/push.html).

>Push is a programming language designed for evolutionary computation, to be

used as the programming language within which evolving programs are expressed.

A  concise introduction to the most recent standardized version of the language

("Push3") is contained in

[The Push 3.0 Programming Language Description](http://faculty.hampshire.edu/lspector/push3-description.html).

## Usage

```clojure

user=> (require '[push.core :refer [push]])

nil

user=> (push 1 2 3)

{java.lang.Long (3 2 1), :exec ()}

user=> (push 1 2 3 "hi" "hello")

{java.lang.String ("hello" "hi"), java.lang.Long (3 2 1), :exec ()}

user=> (push 1 2 3 "hi" "hello" identity)

{java.lang.String ("hello" "hi"), java.lang.Long (3 2 1), :exec ()}

user=> (push 1 2 3 "hi" "hello" #(assoc % :hey "hi"))

{:hey "hi", java.lang.String ("hello" "hi"), java.lang.Long (3 2 1), :exec ()}

user=> (push 1 2 3 "hi" "hello" #(assoc % :exec '()))

{java.lang.String ("hello" "hi"), java.lang.Long (3 2 1), :exec ()}

user=> (push 1 2 #(assoc % :exec '()) 3 "hi" "hello" #(assoc % :exec '()))

{java.lang.Long (2 1), :exec ()}

; push is just a shortcut for push-exec, followed by execute

user=> (push-exec [1 2 3 4])

{:exec (1 2 3 4)}

user=> (execute (push-exec [1 2 3 4]))

{java.lang.Long (4 3 2 1), :exec ()}

user=>
