There is more to do, switches on consecutive numbers are very unlikely, so array solutions don't prove anything, even if the example is so simplistic.

Arbitrary keys in dispatch tables need hashes.

Furthermore all my solutions are able to define a "default" case, like given/when does.

Then goto's allow jumping to multiple lables leading to the same code, for this you need multiple entries in a dispatch hash.

And it should be clear (but mostly ignored/assumed in this thread) that given/when's linear testing of conditions is more flexible then switching to code by literal keys . (C-style I suppose)

The latter is an important but limited sub-case, which is ideally optimized under the hood, but measuring both side by side is like comparing apples and oranges.

yes but you made (rather bold) statements about the execution time of "sub-calls" by benchmarking these arbitrary snippets.

edit

Better you concentrate on this point and try variations on the number of cases.

I hope its evident that "clean" benchmarks are not trival.

  • 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 or How to display code and escape characters are good places to start.
