Re^3: Use method/function signatures with Perl
in thread Use method/function signatures with Perl
Perhaps the codebases we work with are quite different, but almost every case I've encountered of people passing the "wrong" number of arguments arose because someone changed the signature of some subroutine and neglected to hunt down every use of it.
Of course, one response to that is "don't do that", which is certainly valid to some extent. However, with a sufficiently large codebase, and a sufficiently large number of developers with mixed skills and experience, and a language like Perl where tracking down all uses can be challenging to the best of us, there may be something to be said for paranoia.
