[ruby2] will $ for global disapears in ruby2?

Hello!

I remember some posts saying that $ for globals will disapear from ruby2. Is it
still the case?

If I correctly remember arguments for that disapearance are:

1) short globals $', $:, etc, are too cryptic (and perlist)
2) globals are not good/true OO
3) globals may instead be managed through some module or class

module Globals
@my_global = "default value"
class <<self
attr_accessor :my_global
end
end

puts Globals::my_global # => default value

$-variables will not disappear. Some of perlistic $<figure> variables
might.

What about optional strong typing and multimethods in ruby2? I saw a lot of
people wanted that with that thread a while back "What would you most like
to see in the next ruby", is that ever going to happen?

Is there a ruby2 white paper or something?

Too bad for me, I was thinking about writing an RCR that would reuse the $ sigil.
