Comment:
It's generally unwise to rely on the order that trace's will be evaluated,
and thus their output displayed. It could be that due to lazy evaluation
the traces are necessarily evaluated in the opposite order to that which
you expect, or if the strictness analyser has determined that the result
is strict in both of them then it would not be a bug for either order to
happen.
Without a testcase I can't say more.
Thanks
Ian
