Subject: Problem with Array#delete

Hello, I'm baffled by the following problem:

I have an Account class and an external array that keeps them in a list. I'm 
trying to delete the account objects one at a time as needed, by:

class Account
	def quit
		array_name.delete self
	end
end

However, this is deleting every account in the list (array_name == []). I've 
verified that the account objects are unique. Just for an example, this is 
the equivalent of what's happening:

class Account
	def quit arr
		arr.delete self
	end
end

a1 = Account.new
a2 = Account.new
arr = []
arr << a1
arr << a2
a1.quit arr
arr #=> []


Has anyone else experienced this problem, or know what the likely cause is? I 
have other arrays that work in the exact same fashion and work as expected.

Thank you for any help,
Matt
