it is a syntax error.

Depends on your version of Perl. It's called a index-value slice. It returns key,val,key,val,...

Really? In which release of perl did that work then?:

C:\test>\perl5.18\bin\perl -E"my %h=1..10; my $r = \%h; print %{ $r }[ + 1,2 ];" syntax error at -e line 1, near "}[" Execution of -e aborted due to compilation errors. C:\test>\perl5.18\bin\perl -E"my @a=1..10; my $r = \@a; print %{ $r }[ + 1,2 ];" syntax error at -e line 1, near "}[" Execution of -e aborted due to compilation errors.

Or is this a preview of Yet Another Mis-Feature that'll have to be deprecated in a year or so?

It will be sad indeed to see Perl die as a result of self-inflicted injuries.


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

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.
