/******************************************************************************
 *	Notes about dojo.io design:
 *	
 *	The dojo.io.* package has the unenviable task of making a lot of different
 *	types of I/O feel natural, despite a universal lack of good (or even
 *	reasonable!) I/O capability in the host environment. So lets pin this down
 *	a little bit further.
 *
 *	Rhino:
 *		perhaps the best situation anywhere. Access to Java classes allows you
 *		to do anything one might want in terms of I/O, both synchronously and
 *		async. Can open TCP sockets and perform low-latency client/server
 *		interactions. HTTP transport is available through Java HTTP client and
 *		server classes. Wish it were always this easy.
 *
 *	xpcshell:
 *		XPCOM for I/O.
 *
 *	spidermonkey:
 *		S.O.L.
 *
 *	Browsers:
 *		Browsers generally do not provide any useable filesystem access. We are
 *		therefore limited to HTTP for moving information to and from Dojo
 *		instances living in a browser.
 *
 *		XMLHTTP:
 *			Sync or async, allows reading of arbitrary text files (including
 *			JS, which can then be eval()'d), writing requires server
 *			cooperation and is limited to HTTP mechanisms (POST and GET).
 *
 *		<iframe> hacks:
 *			iframe document hacks allow browsers to communicate asynchronously
 *			with a server via HTTP POST and GET operations. With significant
 *			effort and server cooperation, low-latency data transit between
 *			client and server can be acheived via iframe mechanisms (repubsub).
 *
 *		SVG:
 *			Adobe's SVG viewer implements helpful primitives for XML-based
 *			requests, but receipt of arbitrary text data seems unlikely w/o
 *			<![CDATA[]]> sections.
 *
 *
 *	A discussion between Dylan, Mark, Tom, and Alex helped to lay down a lot
 *	the IO API interface. A transcript of it can be found at:
 *		http://dojotoolkit.org/viewcvs/viewcvs.py/documents/irc/irc_io_api_log.txt?rev=307&view=auto
 *	
 *	Also referenced in the design of the API was the DOM 3 L&S spec:
 *		http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407/load-save.html

	//		a function that may return other "partial" function which can be

	//		the original function is reached, at which point the underlying
	//		function (func) is called in the scope thisObj with all of the
	//		accumulated arguments (plus any extras) in positional order.
	// examples:
	//		assuming a function defined like this:
	//			var foo = {
	//				bar: function(arg1, arg2, arg3){
	//					dojo.debug.apply(dojo, arguments);
	//				}
	//			};
	//		
	//		dojo.lang.curry() can be used most simply in this way:
	//		
	//			tmp = dojo.lang.curry(foo, foo.bar, "arg one", "thinger");
	//			tmp("blah", "this is superfluous");
	//			// debugs: "arg one thinger blah this is superfluous"
	//			tmp("blah");
	//			// debugs: "arg one thinger blah"
	//			tmp();
	//			// returns a function exactly like tmp that expects one argument
	//
	//		other intermittent functions could be created until the 3
	//		positional arguments are filled:
	//
	//			tmp = dojo.lang.curry(foo, foo.bar, "arg one");
	//			tmp2 = tmp("arg two");
	//			tmp2("blah blah");
	//			// debugs: "arg one arg two blah blah"
	//			tmp2("oy");
	//			// debugs: "arg one arg two oy"
	//
	//		curry() can also be used to call the function if enough arguments
	//		are passed in the initial invocation:
	//
	//			dojo.lang.curry(foo, foo.bar, "one", "two", "three", "four");
	//			// debugs: "one two three four"
