    Yes, lots of code would have to be changed (in a trivial way) if we
    switched this around now.

I can believe you are right, but here's my reason why I think the amount
of change could be small: The change only affects non-commutative
predicates.  Most of the predicates I have used and that I have seen are
commutative, basically EQ, EQL, EQUAL and /=.

    I think that an incompatible change like this
    has no chance of passing if the reason is just someone's view that the
    order of arguments would be more intuitive if switched around.

Here's a quick test/poll.  Without using the -IF or -IF-NOT functions, 
 - Remove all elements of a sequence which are less than 3.
 - Find the first element of a sequence which is more than 3.
My "intuition" for coding this gives the wrong answers.
I know this doesn't show anything about language design.
