Hmm. I was just reading on use.perl.org and Damian said this:
Magic $^ variables are only magic in that they allow a
subroutine to be declared without an explicit sub keyword or an
explicit parameter list. Instead, their parameter list is
constructed implicitly: it's just the alphabetically sorted list
of the names of all the magic $^ variables within the block.
So I may be wrong about { $^foo * $^bar } being equivalent to
{$^a * $^b }.
Waiting for the Damian or the Larry to chime in ...
