I think you should point out that when you do
my %newSource = %$source; # dereference it all at once
you are not just dereferencing $source
but making a new and independent copy in %newSource
. This may have implications if the code evolves. Any change made to one array will not be reflected in the other, for instance an element removed from %$source
is not removed from %newSource
and the removal of $source
will not imply removal of %newSource
