Can we leave this until 1.4 ? Nokogiri uses id2ref to map from a
pointer to a ruby object. Since this usage is going to be pretty
common in FFI, I can make a specific api for it, but thats not going
to happen overnight.
Besides .. you need to leave some of the performance bullets in the
magazine for future releases :)
