There is a check-at-runtime feature in the UNIVERSAL namespace called can. You can ask a blessed object if it can(domethod), for example, which has slight benefits over asking the object if it isa(MyClass).

But this won't get you very far to checking your code for correctness, which generally needs to happen at compiletime. This can be difficult for the reasons the other folks have already explained: in Perl, compile time is anytime.
