absolute_path

        # RubyVM::InstructionSequence.absolute_path

(from ruby core)
### Implementation from InstructionSequence
---
    absolute_path()

---

Returns the absolute path of this instruction sequence.

`nil` if the iseq was evaluated from a string.

For example, using ::compile_file:

    # /tmp/method.rb
    def hello
      puts "hello, world"
    end

    # in irb
    > iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
    > iseq.absolute_path #=> /tmp/method.rb
