$ ls | perl -l72pe1

This works and seems equivalent to

$ ls | perl -l72pe "{}"

But I don't understand the role of "1" (or digits in general) at the end of the command line, and I can't find any explanation in perlrun. I thought that they might affect the way that arguments are processed, but that doesn't seem right. Can someone clarify?

Thanks,
