Gah, you're right. I didn't test the seek solution with any pipes, and while I did test things like array refs, I didn't test it with scalars directly (mostly because in the app that I want this for, I've already removed scalars from the possible values this snippet would have gotten). However, looking around, it does look like fileno does the trick; pipes are properly recognized, but anything that's not a filehandle triggers a warning. So eval'ing that away captures non-filehandles correctly - at least, as best as I can tell. Snippet above has been updated to reflect this.

It's not what you know, but knowing how to find it if you don't know that's important
