What I am trying to accomplist is:

  class MyClass
    def addVar(var, val)
      instance_variable_set("@#{var}", val)
      define_method("#{var}")  { || instance_variable_get("#{var}") }
    end
  end

  c = MyClass.new
  c.addVar('aa',10)  # here pops the error
  c.aa   # should return 10

But I get this error:
NoMethodError: undefined method `define_method' for #<MyClass:0x2d01cc0
@aa=10>
        from (irb):4:in `addVar'
        from (irb):8

I know this should work because it's used all over rails.

Advice me please
