How can I create a lazy list from an object? I have an object representing the sequence "1..Inf". I tried creating a Coroutine, and then assigning the Coroutine to an Array, but it only yielded "1":
my @a = $span.lazy; # "1" The coroutine worked fine in a "while" loop, but it didn't work in a "for" loop. This is the implementation (in "ext/Span"): coro lazy ($self: ) { my $iter = $self.iterator(); loop { my $n = $iter.next; return unless defined $n; yield $n; } } I understand that this is not fully specified yet, but I'd like to start writing some tests for it. Thanks! - Flavio S. Glock
