The problem with this is that @ARGV could be non-empty but its elements could be undef or empty strings. So your test for "if (@ARGV)" would pass, but the variable would get assigned an empty string. Consider what happens if the scripts is called like this: 
./prog.pl ""

In this case @ARGV is not empty, but its first element is an empty string.
