Subject: Hashing across different types

Hello, I'm trying to redefine the way a hash works for an object so that
other types will hash to the same bucket. For example:

class A

  attr :name, true

  def eql?( another )
    return true if self.hash == another.hash
  end

  def hash
    @name.hash
  end

  def to_s
    @name.to_s
  end

end

a = A.new
h = Hash.new

a.name = "Bob"
h[ a ] = "foo"
print "Value: " + h[ "a" ].to_s + "\n"



The values of "a".hash and of a.hash are the same value (100), so
wouldn't h[ "a" ] be the same as h[ a ]? 

The result of running the above code is: "Value: " (h[ "a" ] returns
nil). Anyone have any suggestions on how I can make this work? Thanks
much.

Nate
