* <code>resume</code>. Arguments passed to resume will be the value of
* the <code>Fiber.yield</code> expression or will be passed as block
* parameters to the fiber's block if this is the first <code>resume</code>.
*
* Alternatively, when resume is called it evaluates to the arguments passed

* or to the block value if it runs to completion without any
