to_binary

        # RubyVM::InstructionSequence.to_binary

(from ruby core)
### Implementation from InstructionSequence
---
    iseq.to_binary(extra_data = nil) -> binary str

---

Returns serialized iseq binary format data as a String object. A
corresponding iseq object is created by
RubyVM::InstructionSequence.load_from_binary() method.

String extra_data will be saved with binary data. You can access this
data with
RubyVM::InstructionSequence.load_from_binary_extra_data(binary).

Note that the translated binary data is not portable. You can not move
this binary data to another machine. You can not use the binary data
which is created by another version/another architecture of Ruby.
