Recently in Matching First Character of Strings Efficiently there was a controversy about the utility of optimizing some bit of code for speed.

On one hand, playing with code optimization is fun and others' code can display enlightening and potentially useful techniques.

On the other hand, Knuth, among others, claim that "premature optimization is the root of all evil", for a few reasons:

• You can easily waste more time and money optimizing code than you will save in running it
• Optimized code often has a funky, fragile structure that is hard to modify or generalize down the line.
• Optimized code is often hard to read, and/or things are done in inexplicible ways.

Because of these problems, we should not encourage novices by indulging in such 'evil' speed optimization challenges.

How can we reconcile these two points of view?

Well, perl golf has a lot of the same issues that speed optimization does. The nice thing about calling some attempt at keystroke optimization 'golf' is that it at once gives a sporting flavor to the challenge, and reminds others that it is only a game, not a production technique.

I propose that we prepend speed optimization games with something like 'sprint', so that we can have fun without the regret of leading others down the path of darkness.

• 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).
