As we saw earlier, "zip" produces little arrays by taking one element
from each list in turn, so
(0..2; 'a'..'c') ==> my @@tmp;
- for @@tmp.zip { say }
+ for @@tmp.zip { .say }
produces [0,'a'],[1,'b'],[2,'c']. If you don't want the subarrays, then
use C<each()> instead:
(0..2; 'a'..'c') ==> my @@tmp;
- for @@tmp.each { say }
+ for @@tmp.each { .say }
and then you just get 0,'a',1,'b',2,'c'. This is good for
