indeed, that actually is intentional. the namespace for variables and methods 
at the same level (instance or class) is the same. thus:

	self.c = 1

would conflict with:

	def c
	   1
	end

notice what happens though. in either case the result is the same:

	puts c  #--> 1

whether c was defined as an instance variable or an instance method.

the above is the reason why instance varaibles would loose the prefix.

technically, these are methods. aren't they?
