Sorry, there was a misprint in the crucial line of my last
mail. Here comes the hopefully correct version:

> class Foo
>     attr_reader ... # here I forgot :pos
>     def initialize
>         ...
>         @pos = ...
>     end
> end
> ...
> blabla = someClass.someMethod.link_to_another_class.methods_pos.pos

> Formally, the system is right: I forgot to declare the read
> access method for the variable pos.

> But:
> (1) the system should tell me which method in the above

> (2) as a naive programmer, with a background in other languages,
> I do not think of pos as method. I think of it as variable.
> Once the system does not find a method, it could check whether
