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

not that i can think of. there might be others to correct me, though.

print @{$data}[0] is too many bracey-curly-making-me-hit-shift characters. they perform the same tasks.

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).	[reply] [d/l] [select]

hmmmm, which means I should have written- `${$data}[0]` :-) -- my $chainsaw = 'Perl';	[reply] [d/l]

`$$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]
