Again, my objection is *not* to the value definitions on their own.  I
was obviously fine with each of them on their own, since I wrote them
that way.  It is precisely the two types of values in combination that
concern me.  Two locally-good decisions can be bad when combined due
to them being inconsistent with each other.

That's why I very specifically brought up the two in concert, to
explore how people intuitively relate the two.

I got 16 responses, which is a good return on the minimal investment I
was willing to put in.  If you'd like to post the question more
widely, feel free.  ^_^  (Though, if you post the question the way you
proposed, I don't think you'd get very useful information - we already
know the answer to what people consider "0deg" to be, and we know what
people consider "left" to be if they only think about that on its
own.)
