and you push a reference to it here.

then you reinitialise it to ().
Question (and answering it will give you your answer).
when you do %show_data=(), what happens?
does it
- create a new hash stored at a new memory location?
- assign an empty hash to the same hash stored at the same memory
location?
would \%show_data be the same or different?
if they it is the same, then would changing %show_data at one place
change its value at all places where it is referenced?
