Just added in optional and rest args for functions:
(fn (a b (o c 5))
(list a b c))
(function (a, b, c) {
c = c || 5;
return [a, b, c];
})
(fn args args)
(function () {
var args = Array.prototype.slice.call(arguments);
return args;
})
(fn (a b . c)
(list a b c))
(function (a, b) {
var c = Array.prototype.slice.call(arguments, 2);
return [a, b, c];
})
I think that's enough for one day. I'm not sure if a simple boolean test is enough for optional args. Perhaps they should test explicitly against undefined?
