Re: meaning of '@' sigil on a hash?

[ikegami]

In Perl5, the sigil represents how the variable should be treated. It does not represent the type of the variable. So just like $ can be used by scalar, arrays and hashes, @ can be used by arrays and hashes.

	select element	select elements (slice)	all keys	all values	all keys & values
scalar	$scalar
array	$array[$i]	@array[@i]	(0..$#array)	@array
hash	$hash{$i}	@hash{@i}	keys(%hash)	values(%hash)	%hash
list		(...)[@i]

This is all documented in perldata, including slices.

Update: Reordered the columns.
