So after ignoring prod after prod, You finally present hunting as a test without giving so much as a hint how that "test" would measure "arrowheadness" and then question why I state that you are unreasonable, irrational and disengenuous?

The apparent outrage at the suggestion of testing functionality started in the first reply to the suggestion.

The apparent outrage

And now you are paranoid. I clearly stated functional tests are sometimes a valid test. In this case, I feel that they are not. You have had every chance to produce your version of a valid functional test with rationale for the test of "arrowheadness". You have failed to do so.
