Design-by-contract in Perl

Language:

Recent development in Perl has popularised around automated test suites.
Object-oriented "design by contract" is a technique which should fit
well with object-orientation, re-use, and Perl's loose types - but it
has been little exploited in Perl. Perl is mutable enough that
design-by-contract can be introduced fairly painlessly.
