Agreed.

In that case I would have the method definition *only* at class level
since apparently it is independent of instance state.  I wouldn't even
have it as instance method at all.  That avoids confusion.  If you
need to invoke the method from instance methods the
self.class.a_method() idiom works well IMHO.

Kind regards
