/**
 * <p>Each JSON record enumerates the disposition of the properties on

 *
 * <p>All records are made of key-value pairs where the key
 *    is the property to process, and the value is the associated
 *    dispositions a.k.a. the "permit". Those permits can be:
 * <ul>
 * <li>The boolean value "false", in which case this property is
 *     blacklisted and simply removed. Properties not mentioned
 *     are also considered blacklisted and are removed.
 * <li>A string value equal to a primitive ("number", "string", etc),
 *     in which case the property is permitted if its value property
 *     is typeof the given type. For example, {@code "Infinity"} leads to
 *     "number" and property values that fail {@code typeof "number"}.
 *     are removed.
 * <li>A string value equal to an intinsic name ("ObjectPrototype",
 *     "Array", etc), in which case the property permitted if its
 *     value property is equal to the value of the corresponfing
 *     intrinsics. For example, {@code Map.prototype} leads to
 *     "MapPrototype" and the property is removed if its value is
 *     not equal to %MapPrototype%
 * <li>Another record, in which case this property is simply
 *     permitted and that next record represents the disposition of
 *     the object which is its value. For example, {@code "Object"}
 *     leads to another record explaining what properties {@code
 *     "Object"} may have and how each such property should be treated.
 *
 * <p>Notes:
 * <li>"[[Proto]]" is used to refer to the "[[Prototype]]" internal
 *     slot, which says which object this object inherits from.
 * <li>"--proto--" is used to refer to the "__proto__" property name,
 *     which is the name of an accessor property on Object.prototype.
 *     In practice, it is used to access the [[Proto]] internal slot,
 *     but is distinct from the internal slot itself. We use
 *     "--proto--" rather than "__proto__" below because "__proto__"
 *     in an object literal is special syntax rather than a normal
 *     property definition.
 * <li>"ObjectPrototype" is the default "[[Proto]]" (when not specified).
 * <li>Constants "fn" and "getter" are used to keep the structure DRY.
 * <li>Symbol properties are listed as follow:
 *     <li>Well-known symbols use the "@@name" form.
 *     <li>Registered symbols use the "RegisteredSymbol(key)" form.
 *     <li>Unique symbols use the "UniqueSymbol(description)" form.
