Execution Order in Execution plan

mUday-Oracle

Along with plan line id, it would be nice if we can see execution order. Will be very helpful for people who do not know how to read plans. Enterprise Manager and SQLT tool does it (though may not be correct order all the time) so now its time to implement natively in the databae.

How the {hot place} do you number "execution order" when multiple steps are carried out simultaneously?
