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

And the rest of the post is a straw man.

Showing that sigils don't indicate the type of value returned is not a straw many to disproving that sigils indicate the type of the value returned.

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.

In the absence of evidence, opinion is indistinguishable from prejudice.

Perl 5.19.4 and above. With hashes it seems fairly useful...

sub new {
   my ($class, %args) = @_;
   my $self = { %args{"foo", "bar", "baz"} };
   bless $self, $class;
}

Used on arrays, a la %arr[1,2,3] it seems less so.
