I think my question can be best understood by example -- what does the following produce?
my @a = 1,2,3,4,5; for @a { .say; @a = (); } My question is whether the change to @a inside the for loop affects the iterator created at the beginning of the for loop. In other words, would the above produce "1\n2\n3\n4\n5\n" or "1\n" ? My followup question is then: my @a = 1,2,3,4,5; my @b = 6,7,8; for @a,@b { .say; @b = (); } I have more examples involving various aspects of list and iterator semantics, but the answers to the above will help guide my questions.
