// Extremely simple serialization framework.
|
|
|
|
// (mis)-features:
|
|
// + Super fast
|
|
// + Very simple
|
|
// + Same code is used for serialization and deserializaition (in most cases)
|
|
// - Zero backwards/forwards compatibility
|
|
// - Serialization code for anything complex has to be manually written.
