Lazy list ACCEPTS any non-iterable

    Also: 

 for ^10 -> $i { say $i ~~ @fib } # Fib is the infinite Fibonacci sequence

is always true, but

for ^10 -> $i { say [$i] ~~ @fib }

is always false.

For usual manners: the bug is present on Rakudo v2022.12 with language version 6.d.

The reason of the behavior is described here: #2468 (comment)

I think this is only a matter of decision: if it's okay for a fix to just not accept any elements when the list is lazy then that's easy to achieve.
