A) The syntax for taking multiple values from the array at once doesn't
make you want to vomit:

5: for my ($t, $s) (0..6) { }
6: for 0..6 -> $t, $s { }

B) The bit between -> and { is now using the same syntax as for any
subroutine argument declaration.

sub something ($t is rw) { $t = 5 }
my $anon = -> $t is rw { $t = 5 }
for 0..6 -> $t is rw { $t = 5 }

Are these fashionable CS ideas or functional programming paradigms?
(Making things read-only by default sure does sound like functional
programming to me.)
