Using the stricture adds, uhm, exactly nothing at all to the above program. It just increases the size of the program text. As for adding -l, I tend to only do that for only liners - with normal programs, you just want to use 'print' without newlines often enough to make it a nuisance (it's still possible by using printf though). I disagree with the remark in update2 though. "Just calling the script using 'perl -l'" is a major PITA. You want to call program by just typing their file names, having to remember which interpreter they need is hard - and it's even harder to remember which program needs which command line options! Not to mention that that will make debugging even harder than having -l mentioned in the she-bang line - that's easier to spot than the -l enforced on the program from the outside.

However, I only write this node because of something else. What's with the quotes around $_ in the print statement? If you're going to nag about (pointless in this case) missing "use strict" statements, and whether or not to use -l vs. a newline, you should at least get rid of the not needed quotes around the variable.
