resume

        # Fiber.resume

(from ruby core)
---
    fiber.resume(args, ...) -> obj

---

Resumes the fiber from the point at which the last Fiber.yield was
called, or starts running it if it is the first call to #resume.
Arguments passed to resume will be the value of the Fiber.yield
expression or will be passed as block parameters to the fiber's block if
this is the first #resume.

Alternatively, when resume is called it evaluates to the arguments
passed to the next Fiber.yield statement inside the fiber's block or to
the block value if it runs to completion without any Fiber.yield
