• First parameter: Delimiter to prefix future nodes
• Second parameter: Current delimiter to prefix current child
• current parent: Parent of the current child
• current child: Child to produce a subtree for; terminates if empty
• depth: Depth of the current child
• index: i, where the current child is the ith child of the current parent
• template: Template to apply to each node (first parameter is the node; depth and index are the tree coordinates, 1-based)
• children: Function mapping a parent to children (first parameter is the node; second parameter is the requested index, 1-based; empty result indicates no more children)
