I was tempted at one point at looking if there is a way to get the number of arguments of a function, but I suppose I got carried away and wrote that .toString() hack :)

Here is the link to my complementary post http://activedeveloper.info/addendum-to-function-currying

Another way of putting all this is perhaps you should also provide the example of curry implemented using papply. To me that is the more obvious one that jumps out from the code, since the body of papply literally appears within the body of curry.

function curry(f){
if(!f.length) {
return f;
}

var args = [];

var c = function() {
for(var i = 0; i = f.length) {
return f.apply(null, args);
} else {
return c;
}
};

return c;
}

Haven’t tested that, but it should work. f.length, not f.toString()! :)
