Hedgehog is a very concise implementation of a
Lisp-like language for low-end and embedded
devices. It consists of a compiler and a byte code
interpreter. The Lisp dialect has proper support
for local and lambda functions, lexical scoping,
variable argument functions, garbage collection,
exceptions, macros, and over a hundred predefined
functions or special forms. The built-in types are
lists, symbols, strings, 32-bit integers, AVL
trees, and tuples up to 16 elements wide.
