in reply to changing copy of a hash changes original

The sub fiddleHash is only supposed to alter hash2 but it also alters hash1

Since you use this my %hash2 = %hash1;, then do this

print %hash2; print %hash1;
Then you will see why!

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
