Subject: Hash as a class variable

Hi ruby fans,

I am a python2ruby switcher and just encountered this problem today
with a class variable:

---
class Testclass
  @@myhash = Hash.new({"a"=>"aaaah"})
  def initialize()
    p @@myhash
  end
end
T = Testclass.new
---
yields
{}

whixh surprises me, becasue I would expect myhash to have an entry and
not be the empty hash. The only way I found to fix this was:

---
class Testclass
  @@myhash = nil
  def initialize()
	@@myhash = Hash.new()
	@@myhash["a"] = "aaaah"
	p @@myhash
  end
end
T = Testclass.new
---
which yields what I expect:
{"a"=>"aaaah"}

I have searched in the FAQ's, Things to know about ruby, websites, etc.
but just couldn't find any hint. Examples are never hashes.

ciao,
   Oliver
