In your IO::File wrapper you should override isa. Why not? It completes the wrap properly. This is a good argument for isa.

Are they grinding you down today? Reusability is based first on usability. Ensuring that good code will interface with the most lousy code possible may be efficacious, but it is not maximizing reusability.1 Instead it's a way to prematurely embrittle the code.

When possible I avoid eval for errors which will be immediately handled.2  So to check if a param can do something, if it even is a blessed thing I'd use these terms in some conditional: 

ref $it and $it=~/=/ and $it->can($meth) and $it->$meth();

1 Having the largest user base doesn't mean the code is more reusable. The word "pandering" begs usage here. It's like that. Stop it, go 'way. Bad word!

2 The "throw" analogy for exceptions is appropriate: raise an exception when you can not handle the problem locally.
