Overview

a JSI Schema Module is a module which represents a schema. a NotASchemaModule represents a node in a schema's document which is not a schema, such as the 'properties' object (which contains schemas but is not a schema).

instances of this class act as a stand-in to allow users to subscript or call property accessors on schema modules to refer to their subschemas' schema modules.

a NotASchemaModule is extended with the module_for_schema of the node's schema.

NotASchemaModule holds a node which is not a schema. when subscripted, it subscripts its node. if the value is a JSI::Schema, its schema module is returned. if the value is another node, a NotASchemaModule for that node is returned. otherwise - when the value is a basic type - that value itself is returned.
