Sorry for the noob question but I couldn't find the answer in existing threads:

I think the common way to generate a Hash of Arrays is using square brackets, something like:

$HoA{$key} = [ @fields ]

but this also works:

@{ $HoA{$key} } = @fields

Are those exactly the same? Is the first preferred over the second for any reason?

I know the second form is used to add elements to the array using push, for instance:

push @{ $HoA{$key} }, @more_fields

Thank you.
