equivelent to, in JSON:

value = { "store": {
	"book": [ 
	  { "category": "reference",
		"author": "Nigel Rees",
		"title": "Sayings of the Century",
		"price": 8.95
	  },
	  { "category": "fiction",
		"author": "Evelyn Waugh",
		"title": "Sword of Honour",
		"price": 12.99
	  },
	  { "category": "fiction",
		"author": "Herman Melville",
		"title": "Moby Dick",
		"isbn": "0-553-21311-3",
		"price": 8.99
	  },
	  { "category": "fiction",
		"author": "J. R. R. Tolkien",
		"title": "The Lord of the Rings",
		"isbn": "0-395-19395-8",
		"price": 22.99

DESCRIPTION

p is a function that injects a property into an object, or pushes a value onto an array.  It takes two arguments.  

p [propertyName,] value

propertyName is any number or string.  value is any javascript value, such as the result of o or a.

If propertyName is not specified, and the current context is an array, it pushes that value onto the array.  
If the current context is not an array, an error is thrown.

---

o builds an object.  It then calls the function specified as the first parameter.  
This can be any Javascript function, but usually it will just be a series of calls to p, each p adding a property.  
Every p must have a propertyName specified.

---

a builds an array.  It then calls the function specified as the first parameter.  
This can be any Javascript function, but usually it will just be a series of calls to p, each p pushing a value.  
Generally, each p will not a propertyName specified, but you can specify if you like.
