===================

Programs are made of links. Links are made of chains. Chains are made of atoms. Atoms have a fixed arity.
Each link's chains are evaluated according to a set of predefined "rules".

Links can be niladic (called with 0 arguments), monadic (called with 1 argument) or dyadic (called with 2 arguments)
Nilads have arity 0, monads have arity 1 and dyads have arity 2

[How to do functions in brainfuck.

Okay. We'll translate the following program into brainfuck, with no thought of efficiency:

char fib (char a){
	switch(a):
		case 0: return 0
		case 1: return 1
		default: return fib(a-2)+fib(a-1)
}
