A delay tree is a superset of a nodal tree (see (container nodal-tree)). It extends nodal trees to allow any entry of the node to be a promise created with the delay operator.
Usage
force-ref node field | [Function] |
Access a field in a node of a delay tree. If the value of the field is a promise, the promise will be forced, and the value will be replaced with the forced value.
