Wow, that's a lot of hate for what seems a fairly obvious way of extending the postfix deref mechanisms to be complete using fairly obvious syntax. Especially since these were proposed many, many years ago and I've seen several expressions of a desire for them to actually get implemented and I don't recall any significant complaints about the idea over those many years.

I personally quite dislike the huge separation between tightly related parts involved in @{ ... }{@keys} when the "..." part can easily spread across multiple lines and involve a quite large number of sequential applications of all manner of postfix deref'ing.

If these are so bad, then surely ->[$i] and ->{$k} have precisely the same problems and should be dropped so that only ${ ... }... can be used. Which would be ridiculous since I see ->[$i] used a ton more than ${ ... }[$i]. I suspect that even @{ ... } will eventually be mostly replaced by ->@* for reasons similar to why ->[$i] is now so much more common than ${ ... }[$i].

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.
