Keep a 'visited' list of elements to ensure we are not going in cycles.

Emit all intermediate elements (along the way).

Emit intermediate elements (along the way), if they meet the given condition. Note that this does not apply a filter on the final elements of the traversal.

Emit intermediate elements (along the way), apart from the first element

Maximum depth to go down in the repeat traversal. Note that there may be other conditions like until|whilst etc.

Stop traversing when given condition-traversal has no result. The condition-traversal is already evaluated at the first iteration, for classic while/repeat behaviour.

n.b. the only reason not to call this while is to avoid using scala keywords, which would need to be quoted.
