Subject: Why no class_variable_set?


I'm looking for a clean way to reflectively set the value of a class
variable. Currently I'm using something along the lines of

class_eval("@@var = #{value.inspect}")

which I don't like much. There is no class_variable_set, but, so I
thought, maybe instance variables of the class object are treated as
class variables, thus I tried

klass.instance_variable_set(:@@var, value)

`@@var' is not allowed as an instance variable name

So, this doesn't work. Then there's

class_eval <<END
  def self.var=(value)
    @@var = value
  end
END
private_class_method :var=
self.var = value

Is this the way to go?
