I've 'borrowed' the following code... 
%a = (
        a => 1,
        b => 2,
        c => 3,
        d => 4,
        e => 5
);

%b = (
        c => 9,
        d => 16,
        f => 36
);

$A=\%a;
@$A{keys %b} = values %b;

which works brilliantly to merge hash b into hash a. What I don't understand is the syntax! Can someone explain what's actually going on here please.
