scooterm,
Not only that, but if the what the list contains is a reference, the reference is replicated as well. The first useful application I remember seeing of this is in tye's Algorithm::Loops. I found a useful variation that looked a little something like:

my @signal = qw(ABRT STOP TERM INT);
@SIG{ @signal } = (sub { kill 9, $pid; exit }) x @signal;

Incidently, diotalevi makes a good point concerning ensuring that you have the same number of things on both sides of the assignment which is not an issue in my example.
