perl -MBenchmark=cmpthese -e'cmpthese -1, { cute => sub { [0,1]->[rand + 2] }, list => sub { qw(0 1)[rand 2] } }'
Rate cute list cute 768000/s -- -74% list 2899719/s 278% --
Yes, the list slice is much faster. But for something that probably runs only once in every 5 minutes, isn't 768000 per second fast enough? Optimizing seems premature here. For things like this, I am against choosing a particular language or syntax for its speed.

I'm not saying that your reply is useless. It's important to know what code does and this information will certainly help some of the readers when they do have to optimize. But the code is written now and not much is gained by changing it, so I'd just let it be. Programmer time is still much more expensive than computer time.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
