Any attempt to elide the existential qualifier in set comparisons will
always produce non-intuitive results. We are saddled with the fact that
"x!=y" does not mean "not(x=y)", that "a=b and a=c" does not imply "b=c",
that "a<b and a>b" can be true, and that "@x=@x" can be false.

I guess it's too late to fix it :-(
