Why does Perl's shift complain 'Type of arg 1 to shift must be array (not grep iterator).'?
- by wes
I've got a data structure that is a hash that contains an array of hashes. I'd like to reach in there and pull out the first hash that matches a value I'm looking for. I tried this:
my $result = shift grep {$_->{name} eq 'foo'} @{$hash_ref->{list}};
But that gives me this error: Type of arg 1 to shift must be array (not grep iterator). I've re-read the perldoc for grep and I think what I'm doing makes sense. grep returns a list, right? Is it in the wrong context?
I'll use a temporary variable for now, but I'd like to figure out why this doesn't work.
