Hi,
Why cant i have an attribute reader for a class variable.
Here's a program.


class SomeClass

 @@var1 = 9 #class var
 def someMethod
    @@var1 = 1
 end

 def initialize
    @var2 = 5
 end

 def getVar1
  return @@var1
 end

 attr_reader :var2
 attr_reader :var1

end #SomeClass ends


  s1 = SomeClass.new
  puts(s1.var2)
  puts(s1.getVar1)
  s1.someMethod
  puts(s1.var2)
  puts(s1.getVar1)
  puts(s1.var1)



Here's the output:

5
9
5
1
nil


Thanks,
Ravi Rao
