Arguments: why not hashes/dictionaries?

Very cool stuff!

Sorry, this is more of a question than an issue, but didn't know where else to ask:

In Objective-C, the names of methods are part of the arguments that you pass
along:

[array insertObject:obj atIndex:5];

The equivalent of the above message invocation in NodObjC syntax would be:

array('insertObject', obj, 'atIndex', 5)

So the even numbered arguments are the parts of the method name that will be
invoked, and the odd numbered arguments are the Obj-C arguments themselves. In
the above example, the insertObject:atIndex: function will be invoked.

How come these arguments aren't just passed as a dictionary instead?

array({
  insertObject: obj,
  atIndex: 5,
});

I'm an Obj-C noob, so apologies if there's an obvious answer and I'm missing it. =)

Great stuff again!

Actually, both of these syntaxes are supported, just the varargs format is "preferred" because of consistency. Consider a method that does not accept any arguments, you could not represent that using an Object, so a String is the only thing we can do:

obj({ method: ??? })  // bad
obj('method')  // good

But actually, both of these will work:

obj({ method: arg })
obj('method', arg)

So really, just use whatever you prefer :)

Cool, thanks. =)
