Syntax for slice of a referenced hash

domo has asked for the wisdom of the Perl Monks concerning the following question:

$ perl -MData::Dumper=Dumper -lwe '$p={}; $p->{qw(fee fie foe)} = (1..
+3); print Dumper $p'
$VAR1 = {
          'feefiefoe' => ''
        };
$ perl -MData::Dumper=Dumper -lwe '$p={}; @p->{qw(fee fie foe)} = (
1..3); print Dumper $p'
Can't coerce array into hash at -e line 1.

You can see what I'm trying to do, can't you? I want to assign an array to a slice of a refernced hash. But I'm damned if I can get the syntax right. I've tried changing quote mthods and diddling with curlies, ->s, $s and and @s until I'm blue in the face, but have had no luck. May I crave the monks' solicitude for my redemption?

Work with the hash more directly: `use Data::Dumper; my $p = {}; @$p{qw(fee fie foe)} = 1 ..3; print Dumper($p);` [download] HTH Philosophy can be made out of anything. Or less -- Jerry A. Fodor	[reply] [d/l]

Others have answered your specific question. I found that dealing with references could get pretty confusing until I realized that there are only four rules and each is quite simple. - tye (but my friends call me "Tye")	[reply]

Is this what you want? `use Data::Dumper; @{$p}{qw(One Two Three)} = (1..3); print Dumper($p);` [download] Prints: `$VAR1 = { 'Three' => 3, 'Two' => 2, 'One' => 1 };` [download] Update: Blast you, arturo, and your quick typing. ;-) bbfu Seasons don't fear The Reaper.

Change `$p->{qw(fee fie foe)}` to `@$p{qw(fee fie foe)}` Then it'll work - Ant	[reply] [d/l] [select]

Slightly belated thanks to those who replied. I'll be adding those rules to my rosary.	[reply]
