Not needed. Perl assume zero if a non-existing element is used in an
arithmetic expression.
perl -e '$a[$_] += int(rand(10)) for 0..10;print"@a\n"'

Perl has no date type. All dates are either strings or numbers. You can use
any string as the keys to a hash. Numbers would be convert to strings if they
are used as keys.

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy..
