After
that speech about not giving a compatible example -which is not at all
relevant in regard to this question, it is a simple see and confirm my
suspicions or not- I think it is quite a arrogant way to address the

leaves me with a bad taste in my mouth and it is a
shame.

Because it's
explicitely coded, I think it's
intended.

what you want.
