I am with brother Tanktalus. I would like to add that the usage of Readonly is also a Perl Best Practice. if you can, use it unless the performance issue is more important to you. The constant in Perl is a bit ugly, In Perl6 they will fix it, see Make constants look like variables for the limitations of constant and how they will solve it in Perl6.
