If the conditional is false, its not clear if the variable will be false, undefined, undeclared, or what. It's much more straightforward to make variable declarations separately. .PP .Vb 4 \& my $foo = $baz if $bar; #not ok \& my $foo = $baz unless $bar; #not ok \& our $foo = $baz for @list; #not ok \& local $foo = $baz foreach @list; #not ok .Ve .SH CONFIGURATION .IX Header "CONFIGURATION" This Policy is not configurable except for the standard options. .SH AUTHOR .IX Header "AUTHOR" Jeffrey R.
