kmizu / Example.mini
Created November 14, 2011 16:22 — forked from kishida/MiniParser.scala
Toy language with parser combinators of scala, which is derived from Kishida-san's code. Original language has dynamic scope. But It has static scope and so-called lexical closure.
val factorial = (n) => {
if(n < 2) 1 else (n * factorial(n - 1));
};
println("factorial(3) = " + factorial(3));
def mkcounter(n) = () => {
n = n + 1;
n
};
val counter = mkcounter(6);
