  • Just spotted a minor typo in the article and I thought I'd tell you so that you might be able to update it.

    The string that separates the elements of an array when expanded in a double quoted string is stored in $". Once again, it's simple to change it to a different value.
      my @arr = (1, 2, 3);
        local $" = '+';

        print "@arr";

    This code prints 1+2+3".

    That final quotation mark shouldn't be there. :)

    Otherwise a very good article.

    All the best,
