Argument is fallacious :) Since it would also be the case if I wrote

I always get confused by ordering: if
x < y
which has the higher priority, x or y? If like integers, y is bigger,
though I usually associate bigger integers with lower priority!
But the notation also suggest x is "above" y in a lattice.
And indeed for boolean
x < y MEANS x implies y
that is
x --> y
which is not at all intuitive. Anyhow just a rant ... :)
