Re: Re: Re: Re: Sad newbie question about Data::Dumper and array references..

Actually, @{$data}[0] and $data->[0] perform slightly different tasks. The former creates an array containing one element (hence the @ at the start), whilst the latter creates a scalar (hence the $ at the start).

`$$data[0]` [download] would suffice. However while style may be the only reason to prefer one over the other, in this case style aids comprehension. I far prefer seeing: `$data->[0]` [download] all day.	[reply] [d/l] [select]
