May be this is because condition part of 'if' is within outer scope?
I guess that this is done for convenience - that is people could easily
write similar to your construct.
unless (open my $fh, "....") {
die "couldn't open";
}
# which is similar to
open my $fh, "..." or die "....";
# use $fh here
BTW if (condition) {...} expands to condition && do {...};
