  • There is no reason to use Text::CSV_XS or any other CSV module. For a csv file? Why is that?
  • (The /e flag stands for eval.) No sir, the /e modifier does NOT means eval.
    This is what perlop said about it; A /e will cause the replacement portion to be treated as a full-fledged Perl expression and evaluated right then and there. It is, however, syntax checked at compile-time.
    It is when you have /ee, that the second "e" evaled, the expression. Please read it up.

    Because perl natively supplies a simple and efficient tool to do what the op wants.

    It is evaled when you have /ee, that the second "e" evaled, the expression. Please read it up.

    I originally had two ee's, but that was so slow compared to split(), I changed it to one e.

    It is, however, syntax checked at compile-time.

    ++ perl savoir-faire.
