Subject: Re: [Q] how to well-qualify the 2-inherited methods at their collision point

David, greetings. thank you for your code and adjustment to my
recognition.

oh! we can customize any module as the 1st class object.
and your 2nd sample code has a scent of java slightly :-)
this is good for after-lunch.

it's not a collision but layered!  make sense.
this adjustment helps me to understand the later Trans's mail more.

i understood. that's true. i agree.
i this matter, what i'd like to do is not a jump but a branch.
so, your code helps me a lot.

your's not so hacky, since it is enough self-descriptive, i think.
