Few queries about Ruby implementation

Hi All,

I have few questions about the current Ruby implementation. It would be
great if someone could help me out with this:

  1. Extendability of Ruby: Is it static or dynamic? Should the extensions
    in ruby implement static functions or are the extensions called
  2. Is there any information /documentation about the next Ruby release
    version ( Ruby 2.0) or what are the proposed updates in the next Ruby
    implementation release?
  3. In case any one has tried implementing a Ruby Uno bridge( or any
    bridgebetween two languages), can I get some documentation about the
    basics steps to be taken while writing the bridge, the bridge
    architecture, the approach document ?
