Fiber exists before require 'fiber'

Ruby

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’
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! :wink:
