Subject: Assigning blame?


'allo

Say I have two classes:

class Bloke
	attr_reader :name
	def sellSoul(aDemon)
		aDemon.buySoul(self)
	end
end

class Demon
	def buySoul(aBloke)
		# if aBloke called the method, OK. Else, tell them where to go.
		puts("I bought #{aBloke.name}'s soul!")
	end
end

Tim = Bloke.new
Tim.name = "Tim"
Satan = Demon.new
Tim.sellSoul(Satan)

I would like the buySoul method to work only if the Bloke calling it is
the same instance of Bloke named, but I can't find any way to determine
what object called a given method. Does anyone have a suggestion?

Cheers
