It works because that's the syntax for a hash slice--slices
use the @ to signify multiples of things.

Perhaps so. Which is why ...

Well, "taken care of" if you think it's broken--not everyone does.

For the sake of discussion:
my %hash = ( a => 1, b => 2, c => 3 );
print "%: ", %hash;
print "keys: ", keys %hash;
print "vals: ", values %hash;
print "[EMAIL PROTECTED]: ", @hash{ qw( a b c ) };
print "[EMAIL PROTECTED]: ", @hash{ keys %hash };
print "[EMAIL PROTECTED]: ", @hash{ sort keys %hash };

%: c3a1b2
keys: cab
vals: 312
@1: 123
@2: 312
@3: 123
