What's the for doing, there? Doesn't this work?

$b and $a->{'b'} = $b

edit: Doesn't solve the problem fully.

    foreach loops sets $_ to refer to the current value in the list which is being iterated. In this case, the list consists solely of $b.

    Your expression is equivalent, but it's not an acceptable answer since the question was about removing the need for using $b twice.
