In my usages, it also has a role in making my intentions clearer.
I agree that, technically, using "return VAL" instead of simply
"VAL" at the end of a perl function is redundant, but that's a good
redundancy IMO, because it makes the code more explicit *for the
sake of human readers*.  You may disagree and state that the extra
noise thus introduced in not worth the extra clarity, but here we
are in the realm of tastes and personal opinions.
