the problem with that is undef opens a temporary file

:) its http://search.cpan.org/perldoc/Dancer::FileUtils#read_file_content

sub open_file {
    my ( $mode, $filename ) = @_;

    open my $fh, $mode, $filename
      or raise core_fileutils => "$! while opening '$filename' using m
+ode '$mode'";

    return set_file_mode($fh);
}

sub read_file_content {
    my $file = shift or return;
    my $fh   = open_file( '<', $file );

    return wantarray              ?
           read_glob_content($fh) :
           scalar read_glob_content($fh);
}
