I vaguely remember the meme "use return with no arguments to return false to any context" as received wisdom, but I can't find any such citation.

From perldoc -f return:

If no EXPR is given, returns an empty list in list context, the undefined value in scalar context, and (of course) nothing at all in a void context.
