Very simple JSON validation format

jsonset is a way of expressing an abstract set of JSON documents, much like JSON Schema. However, JSON Schema is complex, implemented inconsistently, and is clearly designed for specifying more "document-like" validations. That's not necessarily bad, and at least it is close to being a standard, but it does not fit my requirements at the moment.

Some examples for before I document things properly:

A document almost always matches itself

{"a":["b","c",4]} in jsonset.loads('{"a":["b","c",4]}') == True

$ is used to denote special directives

"a" in jsonset.loads('{"$union":["a", "b", "c"]}') == True

Here are some directives:

{ "$union" : [ "$string", 42 ] } { "$and" : [ "$string", { "$length" : 5 } ] } { "$array" : "$number" } { "$range" : [ 5, null ] } { "foo" : "$boolean" }

"$$foo" evaluates to the literal "$foo" (escapes for $ past the first one are unnecessary)
