Re^2: unshifting by reference

Thx it works (obvious it was ^^).
But I don't et it, I thought that the "->" dereferences, doesn't it ?
when I did print $this->{N}[0]{Value}; it worked ok, so whats the difference ?
Why didn't I needed to dereference there ?
and whats "Dumper" is this really required ? (I prefer to avoid module dependencies)
Thx again

The thing is that `unshift` needs an array (syntactically), not an array reference. And the way to get an (entire) array from a reference is to say `@$aref`, or `@{ $something->{that}{returns}[1]{aref} }` for more complex expressions. To address a single element of the array, you'd say `$aref->[$index]`. (The Data::Dumper module is to easily print out complex data structures. I just used it for demo purposes — you of course don't need it to unshift the value.)	[reply] [d/l] [select]

`->` is dereferencing a hash that has nothing to do with your question. Your question is about dereferencing the array referenced by `$this->{N}`.	[reply] [d/l] [select]
