I can imagine that someone could come up with a good way to use this feature. For example, in chaining with other code refs. I'm not entirely sure how that would work, but someone might be able to get it to work.

However, I'm pretty sure this particular example would breed nothing but headache and heartache - there is no fallback mechanism here to allow you to say that if Foo-linux.pm doesn't exist, Foo.pm will be fine. Or, if it isn't fine, to print out a usable error message. Because as the user, I'd probably be confused by any error message referencing "Foo-linux.pm" when I had a "use Foo" in my code without some sort of extra information on my screen.

Instead, I would suggest that code that is intended to stack probably should be made into objects that have an INC method (see require). Someone may write a generic "extract from tarball" INC object. If you want to change the name you get from the tarball, you can write your own INC object that wraps the tarball INC object, and changes the name on the way through.

(Note that before looking this up during the writing of this node, I wasn't even aware of INC objects...)
