in reply to Operator Associativity and Eliminating Left-Recursion in Parse::RecDescent

Typo: This line, 
    pow_ : '**' pow { [ $item[2], $arg[0], $item[3] ] }

[download]
should instead be: 
    pow_ : '**' pow { [ $item[1], $arg[0], $item[2] ] }

The correct version is there in the code, but not in its earlier description. Very nice article, thanks!
