# fe

A *tiny*, embeddable language implemented in ANSI C

```clojure

(= reverse (fn (lst)

  (let res nil)

  (while lst

    (= res (cons (car lst) res))

    (= lst (cdr lst))

  )

  res

))

(= animals '("cat" "dog" "fox"))

(print (reverse animals)) ; => ("fox" "dog" "cat")

```

* Small memory usage within a fixed-sized memory region — no mallocs

* Simple mark and sweep garbage collector

* Easy to use C API

* Portable ANSI C — works on 32 and 64bit

* Concise — less than 800 sloc
