On my system, the stack over-flows at count 331.
But the simplest(*) way to get recursive calls to work is often to
break the recursion with a [delay 0] to start a new depth first
execution chain after the current one is finished, or to refactor it
to use [until](+) to iterate instead of recurse.
I attached an example of both techniques.
(*) but it can become unmaintainable in larger patches...
(+) but [bang(--[until] can take a while to finish, be careful...
