		//		additionally, if one of the functions returns an array, the values
		//		of that array are passed to the next function in the composition
		//		as positional arguments.
		//
		// example:
		//	|	var greet = function(name){ return "Hi: " + name; };
		//	|	var exclaim = function(statement){ return statement + "!"; };
		//	|	var welcome = dojo.compose(greet, exclaim);
		//	|	welcome("Pete");
		//	|	// Hi: Pete!
