why do you localize some but not all of the dumper options? local will
make it work only for a call in this scope which is file scope. better

By saving the output of Data::Dumper to a *.pm file, it can be reloaded
via "use".

Dump the data structure for printing.
It's useful for checking the complex data strucure of Perl.
For example,
use Data::Dumper;
my %hash = ( 1 => [1,2,3,4],
2 => { 1 => { 2 => [3,4,5] } },
);
print Dumper \%hash;
Run it and see what is printing.
Also you could check
What is the use of Data::Dumper module?
can any body please give examples?
Have been using perl for some time and never used this module. Not sure if i
am missing something by not using it.
Thanks,
