Key features:
- Serializes any closure and arbitrary objects
- Doesn’t use eval for closure serialization or unserialization
- Handles all variables referenced in use(), recursive closures, static closures and magic constants
- Automatically resolves all class names, function names and constant names used inside the closure
- Track closure’s residing source by using the #trackme directive
- Simple and very fast parser
- Proper exception handling for unserialized closures
- Supports cryptographically signed closures
- Provides a reflector for serialized closures
- Automatically detects when the scope and/or bound object of a closure needs to be serialized in order for the closure to work after deserialization
