pugs> map { "Element $^a is called $^b" }: @array.kv;
("Element 0 is called london",
"Element 1 is called bridge",
"Element 2 is called is",
"Element 3 is called falling",
"Element 4 is called down")
But it can hardly be blamed for clarity.
That's a little unfair. Choose good names and it's perfectly clear:
map { "Element $^array_index is called $^array_value" } <== @array.kv;
Likewise, for your original formulation:
for @array {
say "$^index\t$^value";
}
Given that we already have both placeholders (above) and pointy blocks:
for @array -> $index, $value {
say "$index\t$value";
}
to achieve this task, and given that both mechanisms allow you to choose the
name of the counter variable (rather than being stuck with some unreadable
punctuation variable), I don't think we need a third mechanism for this.
