What makes you think that:
sub rcsname {
(my $file = shift) =~ s/foo/bar/;
return $file;
}
modifies the ACTUAL argument you passed to rcsname()? Only if you had
done
sub rcsname {
$_[0] =~ s/foo/bar/;
}
or passed a reference and done
sub rcsname {
my $file = shift;
$$file =~ s/foo/bar/;
}
or some other specific effort would you have modified the argument to the
function.
