The other way to deal with it is to use split /,/ anyway, and then just know that there is a comma at the end of the string. You could even stick it back on if you wanted to.

But it makes me wonder why you want the comma. I bet you really want foo1, not the quotes, not the comma. Probably if you re-consider whatever processing happens next, your code might simplify.

Or maybe I'm wrong.
