Need Help??

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

Is there a way to initialize an anonymous hash with the slice syntax ? How would I edit the code below to skip using the %hash variable ? This is not important code wise, but not knowing how to do it is killing me.

 my %hash;
 @hash{ @labels } =  @values;
 $data->{keys_and_values} = \%hash;

Do you mean something like `@{ $data->{keys_and_values} }{ @labels } = @values;` ?	[reply] [d/l]

however, if you use strict; you must declare `my %hash;` [download] does anyone know otherwise?	[reply] [d/l]
