For instance passing more args to a subroutine than it needs should IMO not be viewed as a bug. Its behaviour that many a perl programmer would consider completely normal.
We've touched this discussion before (Re: Re: Re: Context aware functions - best practices?). I do not agree. There is no concensus on what will happen with the extra arguments. I'm a firm believer of that documentation is what decides what should be considered a bug or not. If the documentation says a subroutine takes three arguments then I read that as the subroutine should be given three arguments. I don't read it as the subroutine should be given minimum three arguments.
If everyone would live by "it's OK to pass too many arguments" then there would be a lot of unnecessary incompatible updates (i.e. when the module author adds an argument to the subroutine interface). If everyone would live by "it's not OK to pass too many arguments" then module authors wouldn't have to worry about extending the subroutine interfaces and the number of incompatible updates would be reduced.
Assuming that passing too many arguments is silently ignored is to assume things about the implementation, and assuming things about the implementation is by general concensus evil.
Just because it works now doesn't mean it'll work tomorrow--unless documented to do so.
