It's a personal value judgement.

Indeed, and as such is not a persuasive argument. Re-reading jonadab's post, it does seem he was simply relaying his own opinion. I suppose I could have ignored that paragraph in my reply altogether. Note that I wasn't really trying to persuade anyone to use IO::All, just pointing out a "weak argument," even though it now appears it wasn't an argument at all. I guess it's safe to completely ignore that part of my post as well. :-)
