Hi,

obigen Hinweis bekomme ich bei folgendem Skript (/tmp/unbenannt):

Code (perl): (dl )

#!/usr/bin/perl
use warnings;
use diagnostics;

my %var = (foo=>"bar");

sub print_foo
{
        my $ref = shift;
        print %{$ref}->{foo};
}

print_foo \%var;


Aus dem Hinweis lesen heraus das dies nun wohl entfallen ist. Aber wie soll man das nun umsetzen?

$ perl /tmp/unbenannt 
Using a hash as a reference is deprecated at /tmp/unbenannt line 10 (#1)
    (D deprecated) You tried to use a hash as a reference, as in
    %foo->{"bar"} or %$ref->{"hello"}.  Versions of perl <= 5.6.1
    used to allow this syntax, but shouldn't have. It is now deprecated, and will
    be removed in a future version.
