I guess my problem here is why are we worrying about the
cool deference options - when I fear what we should be worrying about is
say
sub eatArray
{
my ($array1, $array2) = @_;
croak "bad first argument\n"
unless( ref($array1) eq 'ARRAY');
croak "bad second argument\n"
unless( ref($array2) eq 'ARRAY');
.....
}
since using
@$array1 and @$array2
is really no mo better than the foo jam above...
ESPECIALLY if they have scragged the values passed.

Where I get to show how the UGLIES get passed in with @_
by way of catching the Croak....
