partial application of parameters, allowing (based on <http://ejohn.org/blog/partial-functions-in-javascript/>)

partial.js

// fn - function to call
// signature - array of arguments to use to call fn, if an array value is `undefined` 
//   then use the curried/partial function parameter
function partial(fn, signature) {
    var slice = Array.prototype.slice;

    return function apply() {
        var args = slice.call(arguments);
        return fn.apply(fn, signature.map(function fillIn(arg) {
            return arg === undefined ? args.shift() : arg;
        }));
    };
}

zz node console

> var log = console.log.bind(console)

> var argLimit = partial(log, [undefined, undefined]);
> argLimit(1, 2, 3, 4);
1 2

> var argMash1 = partial(log, [1, undefined, 3, undefined]);
> argMash1(2, 4);
1 2 3 4

> var argMash2 = partial(log, ['the array item value is', undefined, 'the array item index is', undefined]);
> [11, 22, 33].forEach(argMash2);
the array item value is 11 the array item index is 0
the array item value is 22 the array item index is 1
the array item value is 33 the array item index is 2

> var myLog = partial(log, ['isao', undefined, '=>', undefined])
> myLog(1,2,3)
isao 1 => 2
