Type of arg 1 to push must be array (not private variable)

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

I have this code working on perl 5.18 but when using 5.10 I get the error on the title:

my $data_ref = [];

while (<$fh>) {
    chomp;
    my %temp = /($keys): (.+)/g;
    if (/^\s+Description:\s+(.+)\z/sm) {
        $temp{Description} = $1;
    }
    push $data_ref, \%temp;
}

Apparently according to this Stackoverflow post http://stackoverflow.com/questions/20824920/perl-array-references-and-avoiding-type-of-arg-1-to-keys-must-be-hash-error this is something new since 5.14.

How can I solve this for 5.10? I cannot upgrade that Perl version just yet. Thanks for your help!

FWIW, as Basic debugging checklist teaches, use diagnostics/splain/perldiag Read more... (2 kB) And there you have it Arrays must be @NAME or @{EXPR} :)	[reply] [d/l]
