Bug #5750: Thread.current local-variables behavior
https://bugs.ruby-lang.org/issues/5750

Author: Julien A

Hi, I stumbled upon something which for me is a bug and wanted to check if it is working as intended or not:

    Thread.current[:a] = 1
    p Thread.current[:a] # => 1

    Fiber.new do
     p Thread.current[:a] # => nil
    end.resume


There is clearly a problem in either the documentation or the implementation for me there, we are in the same thread yet the returned values are different which is completely counter intuitive...
Why not add a fiber-variables store to allow the following and keep things separated between fibers and threads

    Fiber.current[:a] = 1
    p Fiber.current[:a] # => 1

    Fiber.new do
     p Fiber.current[:a] # => nil
    end.resume

Which is now the behavior I would expect.
