If I was to judge by available test cases only, I would have decided
DIP1000 is waste of time and brings nothing useful to the table. They
are terrible in showing implementation goals being low level regression
testing artifacts.

Really, do you think anyone will ever be impressed seeing code like
`int* foo1(return scope int* p) { return p; }`? DIP1000 as defined can
allow much more interesting things and tests should show that too, not
just synthetic artifacts.
