My first reaction was, "it probably should reset the iterator". But then I wondered, what if one had written C<< $a [1] = "B" >> instead of C<< @a = "A" .. "C" >>? Should the iterator be reset then? What on C<< @a [0 .. 2] = "A" .. "C" >>? Should shift, pop, push, unshift, splice reset the iterator? Currently none of them do. Even C<< undef @a; @a = "A" .. "C"; >> doesn't reset the iterator.
