I didn't mean to imply that the do wouldn't work, of course. I only meant that you also used the print and return form and that it might fail even inside a do block. Update: Erp. I just re-read your post and saw that the actual code you suggested did not use and so it, of course, wouldn't suffer from that problem. Mea culpa!
You're right about return print "bar" if $foo, of course. That's probably the "best" way to do it, in that it never has a chance of failing but it's a little less clear what's going on... *shrug*
