Hello out there,
why is this

entrypoint rule test() {
	do {
		--OK
		Sequence{1,2,3}->sortedBy(x | x).debug();
		--OK
		Sequence{1,2,3}->sortedBy(x | 0 - x ).debug();

		--outch!
		Sequence{1,2,3}->sortedBy(x | if true then x else 0 - x endif).debug();
	}
}

resulting in this output:

Sequence {1, 2, 3}
Sequence {3, 2, 1}
Sequence {1, 1, 1}

If it is not allowed to use such a body inside sortedBy this statement should throw an exception, not return a totally useless result!?

Regards,
Sebastian
