Consider support partial function application

[dschenkelman]

What do you think about including a function to allow partial application of arguments?
I think it could be a useful addition and can PR it if you would like to.

Example use case: currently I'm working on a plug-in where I need pass parameters when using async.series:

async.series([
      f1,
      f2,
      f3],
      callback);

I'd like to do something like the following without having to include lodash or underscore:

async.series([
      Hoek.apply(f1, request),
      Hoek.apply(f2, request),
      Hoek.apply(f3, request)],
      callback);

Thoughts?

Just to clarify, nothing too complex just:

function partial(f){
  var args = Array.prototype.slice.call(arguments, 1);

  return function(){
    return f.apply(null, args.concat(Array.prototype.slice.call(arguments)));
  };
}

Per the reasons described in #98 (this is not a general purpose module) I'm going to decline on this one.

I see, didn't know about that. Thanks for clarifying!

@dschenkelman couldn't you achieve that with either bind or async.apply?

[dschenkelman]

@arb +1 for bind. We ended up getting rid of async to use items, but bind would work :)
