Both are correct. The specific call to oct() is useful if the mode
is stored in a variable, or is a string.[1]

Removing oct() would be a micro-optimisation at best, and could
potentially introduce a hard-to-track-down bug:

    1.    my $mode = 0644 ;
          chmod( $mode, $file );

    2.    chmod( '0644', $file );

    3.    chmod( 0644, $file );

You need oct() in the first 2 cases.
