Fiber exists before require 'fiber'

[Roger Pack]

So, in 1.9 it appears that the Fiber class exists before you've required
fiber. Thoughts?

irb(main):001:0> Fiber
=> Fiber
irb(main):002:0> Fiber.current
NoMethodError: undefined method `current' for Fiber:Class
from (irb):2
from /Users/rogerpack/19/bin/irb:12:in `<main>'
irb(main):003:0> require 'fiber'
=> true
irb(main):004:0> Fiber.current
=> #<Fiber:0x11bb10>

And, oddly, only fiber.bundle exists, not fiber.rb

is this more like 'supplemental fiber methods' or something?
Anyway it works, I'm just curious.
Thanks!

Without the require, you get asymmetric fibers: they're useful as
generators. With the require, you get symmetric ones, which are closer
to coroutines.

Nope, that's not confusing at all! ;-)
