return values evaluating to true

Hi, I have a snippet of code as below. Even when I return 0 or '', why does @blocks evaluate to true? If rows returned are 0, then if(@blocks) should evaluate to false, correct? Thanks, Radhika --- use strict; use diagnostics; my @blocks = (); sub do_something { my @row = @_;
