is reusing alias names in multiple foreach blocks safe?
I just run a script in which I reuse some of the alias names in
different foreach blocks (by careless copying). it is like:
...
b = foreach a { x = ...; y = ...; ...}
...
i = foreach h { x = ...; y = ...; ...}
It finished and the results look ok. Can someone confirm that alias
names can be used repeatedly in different foreach blocks?
Regards,
Xiaomeng

Yes, that is safe.
