Why wouldn't you want an interface to the class?
Profiles are a pain, but that doesn't mean you can't define
a solid interface.
Design by contract is well-supported, and works (e.g.
Class::Contract). The difference with Perl is that you
explicitly code the tests -- instead of using them as
an error-checking crutch in the compiler.
