Style/ClassMethods gets singleton methods wrong

[zenspider]

    UNDEFINED = Object.new # :nodoc:

    def UNDEFINED.inspect # :nodoc:
      "UNDEFINED" # again with the rdoc bugs... :(
    end

Could you elaborate on the nature of the problem? This code should be ignored by Style/ClassMethods.

Sorry, I should have included the output.

Ah, I think I get it now. We're currently walking through all static method definitions inside the bodies of classes and modules and check if their names are prefixed with a constant (but we don't care what that constant is as we've assumed it's the class/module name). We should actually check if that constant is the name of the containing class/module.
