(Assuming the PM is sooner alive than dead & I can still read/write here), I noticed some cpan modules have a label (the _: to be specific, mostly in modules by SPROUT, but also perl itself if example is needed) at the end of a sub; it's deparsed into () i.e. empty list. Why? Is this behaviour documented anywhere?

In reply to Label makes a sub to return empty list -- "secret"? documented? by Anonymous Monk
