Perl 4 did that, but the feature was lost in Perl 5.

Every once in a while someone suggests adding it back to Perl 5, and what happens next is that everyone jumps in and suggests one stupid bonus feature after another. "Oh, it should do XYZ also." "Yes, and PDQ as well." After that, it sounds too complicated so nobody wants to do it.

Damian Conway has an implementation of a switch statement based on source filters, but I think all it does is compile your code into an if-elsif internally; you don't get the optimization that you would get in C.

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.
