(1) Don't worry about performance unless there's an obvious performance problem. Especially don't worry about the performance of little features. This is called "premature optimization."

(2) When you DO find a serious performance problem, attack the worst performance areas first. How do you know what's the worst? You Devel::Profile the code as a whole and Benchmark alternatives. Profiling and Benchmarking is the only sane way of discovering what portion of your program is taking the most time. Update: clarified myself reflecting L~R's corrections.

(3) The specific feature you mention should have almost no effect on execution time, since the function name is entered into both symbol tables. The only difference I would guess would be how long it took the parser to parse the extra four tokens.

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.
