Here you can find some real use json for testing, including a big one

Thanks for testing! My JsonStorage seems to be outsider. =)

Actually, my work requires more effective serializers, such as
Protobuffers, ASN.1 or Thrift. But I shoose Bencode, it simple and almost
human-readable text, but fast and compact as binary.

Most serialization protocols use same data structures - numbers, literals,
lists and records. Pascal type Variant suitable for any data, except
records (dictionary, name-value pairs). So, if we add records to Variant,
it will become serializable/deserializabe to many protocols. Also, it can
be used to store publushed properties and used to transfer data between
different objects/classes/records, that supports RTTI.

Even without RTTI, Variants can be used to store name-value pairs as
name-indexed array, it very handy, and present in many modern programming
languages. "Variant record" can be static, initialized once, like
VarArrayCreate(), don't allow appending new name-values.
