( #3333=superdoc: print w/replies, xml ) Need Help??

Last I checked, Perl6 was also supposed to support decoupling the key comparison from the extraction of keys from list elements. In Perl5, key extraction is conflated with comparison in a single sub, which means the key extraction code for $a is often copypasted for $b. Given that key extraction is decoupled from comparison, you’d also often need simple forms of comparison only, so there were ideas being bandied about for a more declarative comparison syntax for those forms.

Now the motivation for all this was to reduce duplication and make the trivial cases simpler, but such syntax would neatly allow the runtime to do ST sorting internally, without the programmer having to do anything explicit about it.

I don’t know what came of it, but I’d be surprised if it hasn’t made it into the current form of Perl6 in some shape. I should go look into this.

Makeshifts last the longest.

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.
