For what it's worth: a couple years ago I thought I saw a condition where multiple failures occured within the eval. I couldn't count on $@ containing the pertinent (meaningful) text for the failure. That's why the eval examples I posted back then included a signal catcher within the eval to capture the $@ text and add it to an array. After the eval, I could test if my array contained > 0 entries and emit all the entries in my warn output. 

Maybe the maintainer can comment on whether that's possible. But, I definitely remember a situation where something like a put/get was failing and I was not getting the real message in $@. Getting control on die and capturing $@ into an array indicated it died multiple times and the first time was the one that had the meaningful message.

Hope that helps,
Mark
