# 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")
```

## Overview
* Supports numbers, symbols, strings, pairs, lambdas, macros
* Lexically scoped variables, closures
* 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
